Firefox 3 most certainly does not, unless you're using Flash, which is a separate problem altogether. I've been considering switching back to Firefox after spending the last two years with Camino.

    Hey thanks for replying.
    Here's what I did:
    First I tried the Winsock reset in the Command prompt. Nothing changed.
    Next, I tried the instructions on http://http://support.apple.com/kb/TS4123. The only other program that came up on the 'Winsock Providers' tab on the program was 2 Windows Live applications, which I can do without. So I deleted all Windows Live Applications.
    I did the Winsock reset in the Command Prompt again and rebooted my comp.
    Unfortunately, nothing has changed. iTunes keeps freezing at various stages of the sync, then shows the candy cane-striped bar with either the words 'Finishing sync' or 'Cancelling sync', before showing the Apple logo.
    Sometimes, iTunes gets to the syncing stage - "Copying # of ####" - where it will trudge through the first, second and third tracks before flashing "Copying 4 of ####" for a split second and I catch "Cancelling sync" briefly before the Apple logo appears.
    Again, I've repeated the steps I mentioned in my previous post. Does ANYONE know when the new version of iTunes is set to be released?! This one is driving me INSANE, to say the least!!

  • Does Apple give you a toll free number to call about possible viruses?

    Does Apple send toll free numbers to call about possible virus or is it a scam

    There are no known viruses for Macs.  There is adware and malware.  For adware, those things that keep poping up in your browser you can use AdwareMedic from thesafemac.com to quickly and easily remove all know adware. 
    That site also have this Adware Removal Guide if you prefer to do it manually thru the Finder.

    -- flash malware.
    ppc -- Power PC.   An older computer processor used by Apple.  Last Mac shipped with PPC was in 2006.

  • Possible virus? MPX player?

    I need help with a possible virus. I was trying to watch a NBA and stream it online. I think it was a mpx player? HELP

    You may have installed the "VSearch" trojan. Remove it as follows.
    Malware is always changing to get around the defenses against it. These instructions are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.
    Back up all data before proceeding.
    Step 1
    From the Safari menu bar, select
              Safari ▹ Preferences... ▹ Extensions
    Uninstall any extensions you don't know you need, including any that have the word "Spigot," "Trovi," or "Conduit" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
    Reset the home page and default search engine in all the browsers, if it was changed.
    Step 2
    Triple-click anywhere in the line below on this page to select it:
    /Library/LaunchAgents/com.vsearch.agent.plist
    Right-click or control-click the line and select
              Services ▹ Reveal in Finder (or just Reveal)
    from the contextual menu.* A folder should open with an item named "com.vsearch.agent.plist" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
    Repeat with each of these lines:
    /Library/LaunchDaemons/com.vsearch.daemon.plist
    /Library/LaunchDaemons/com.vsearch.helper.plist
    Restart the computer and empty the Trash. Then delete the following items in the same way:
    /Library/Application Support/VSearch
    /System/Library/Frameworks/VSearch.framework
    ~/Library/Internet Plug-Ins/ConduitNPAPIPlugin.plugin
    Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
    The problem may have started when you downloaded and ran an application called "MPlayerX." That's the name of a legitimate free movie player, but the name is also used fraudulently to distribute VSearch. If there is an item with that name in the Applications folder, delete it, and if you wish, replace it with the genuine article from mplayerx.org.
    This trojan is often found on illegal websites that traffic in pirated content such as movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow.
    You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the Internet criminal behind VSearch has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing has not done so, even though it's aware of the problem. This failure of oversight has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.

  • Macbook Air Virus?

    my macbook air just froze on me while viewing a photo gallary on the internet. I turned it off, and restarted it. However, all I see is a blank gray screen. I tried Command + R, which prompts a message of Apple searching on Internet, but in less that 5 seconds freezes as well. Did my Mac has a virus now?

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
         a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    Sometimes a boot failure can be resolved by resetting the NVRAM.
    Step 3
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
    Step 4
    Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
    If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
    If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 5
    Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
    Step 6
    Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 7
    Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
    Step 8
    This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 9
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. If you can't get to an Apple Store, go to another authorized service provider.

  • Macbook air virus protection

    what is a good virus protection for the macbook air?

    1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
    OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
    2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
    The following caveats apply to XProtect:
    It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
    It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
    3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
    Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
    It can easily be disabled or overridden by the user.
    A malware attacker could get control of a code-signing certificate under false pretenses, or could find some other way to bypass Apple's oversight, or the oversight could fail in a particular case due to human error.
    For most purposes, applications recognized by Gatekeeper as signed, including App Store products, can be considered safe. Note, however, that at least one trojan for iOS (not for OS X) was briefly distributed by a developer in Russia through the iTunes App Store. That store is under the same oversight by Apple as the Mac App Store, so the protection shouldn't be considered absolute. App Store products may prompt for access to private data, such as your contacts. Think before granting that access. OS X security is based on user input. Never click anything reflexively.
    4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
    5. Beyond XProtect, Gatekeeper, and MRT, there’s no evidence of any benefit from other automated protection against malware. The first and best line of defense is always your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
    That means, in practice, that you never use software that comes from an untrustworthy source, or that does something inherently untrustworthy. How do you know what is trustworthy?
    Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
    A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
    Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
    Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
    Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are in this category, though not all are necessarily harmful.
    Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
    Even signed applications should not be trusted if they do something unexpected, such as asking for permission to access your contacts or your location for no apparent reason.
    6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
    Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
    Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
    Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
    Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
    7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. If you need to be able to detect Windows malware in your files, use the free software  ClamXav — nothing else.
    Why shouldn't you use commercial "anti-virus" products?
    Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
    In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
    By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
    8. ClamXav doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
    ClamXav is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
    A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
    ♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
    ClamXav may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use ClamXav unless a network administrator requires you to run an anti-virus application.
    9. The greatest harm done by security software, in my opinion, is in its effect on human behavior. It does little or nothing to protect people from emerging threats, but if they get a false sense of security from it, they may feel free to do things that expose them to higher risk. Nothing can lessen the need for safe computing practices.
    10. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.

  • MacBook DAME virus. Infected kcn-dump.bin? How do I fix it?

    I opened my macbook and Sophos Free Mac Edition came up with a threat called DAME.  It said that the kcn-dump.bin was infected.  What do I do?  It is somewhere in the /private folder.  There is no option to clean it up, it says it must be cleaned up manually.  However, I restarted my computer, and the threat is no longer coming up.  What is this?  Has it moved to somwehere else?  How could I have gotten this?  How do I clean it?
    this is the exact path its in: /private/var/db/kcm-dump.bin
    Thank you.

    Furthermore, when I clicked the description it brings me to the sophos website where it describes what the virus is and it says it is windows only.
    Correct, it's not uncommon for a Mac to be able to transfer a Windows based virus, so it can appear on the machine (but not affect it, but it can be passed to another Windows machine on the files),  only in the present User account.
    However the pathname you describe is a root level based with the highest degree of security and very highly unlikely a Windows based malware would appear there or that you would be using root user as it's disabled by default.
    The strenght of Unix's security comes from the various permission levels employed, combined with the fact that the malware in question is Windows based, not OS X or Unix based, so it won't even run on a Mac to begin with.
    So since we know there isn't any Mac based viruses, this one being a Windows based one, it's more likely a "false positive" since it didn't appear the second time a scan was issued. Confirmation with ClamXav (runs only when you need it, not always on) should clear it up as a false positive.
    http://www.clamxav.com/
    It is possible you have installed a trojan, software from quesitonable sources, that you gave your admin password too and thus could have infected the root user, but the malware is Windows based (actually it's a
    a polymorphic encryption engine which is used as part of the viruses
    http://wiw.org/~meta/vsum/view.php?vir=364
    However if you didn't install anything from questionable sources, then more likely than not it's a false positive.
    I wouldn't worry about it unless you started noticing more issues.

  • Advice needed on possible virus related prob - please help!

    Evening everyone,
    I previously posted on here about an issue I was having with my external hard drive not mounting. I erased it and got it to mount but now I get an error message saying File could not be transferred as it could not be read or written.
    I have recently come to suspect I might be harbouring viruses on my macbook as one turned up on my pendrive and on some email attatchments I've sent and was wondering if you think this could be causing the problem with the hard drive? If not - what might be? I've read that some people think it's a prob with tiger. Also can anyone recommend some virus software? I know a lot of people use clam but does that work with intel macs? Also I don't know much about the technical side of things and it doesn't look too user friendly - do you think it would be worth buying a full package like Norton?
    Thanks in advance for all of your help!

    Hi Sherman,
    Thanks for your help! The ignore ownership box was already ticked. Tried to repair the disk and it did find errors but the repair did not work - it says that the underlying task report failure on exit. Any more suggestions? Is it not possible that I am harbouring a PC virus - it isn't affecting my mac but could it not be playing havoc with the hard drive? Or is that just broken and I should send it back?
    I am currently studying in spain for the year but am from the UK and will be back there this weekend so am hoping to sort the problem out before then, or go visit the genius bar in london while I am home.
    Thanks again!

  • I have some serious malware or possible virus!!!

    I know some will say viruses aren't possible on a Mac but I have had them on a pc and this is way worse than anything I've ever seen! I've tried erasing my disc in more ways than one, running utility from start up, etc. my macbook has a delay to where my password doesn't show any text in the password login for like fifteen minutes. However I can type the password (nothing shows up in box) and it will appear and login about 10-15 min later. Because of this delay between my mac keyboard and mac itself it will not allow me to run utility from startup. I've tried every way to restore my Mac to no avail! Please help!!!

    Reinstall OS X without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

  • Possible Virus On Bootcamp, how to remove?

    Hi, I think I may have gotten a virus on my windows partition of my macbook pro. I windows XP professional with service pack 3 installed. Last weekend I was booted into windows when it suffered a "fatal error." The computer restarted and windows XP was fine. I did, however, get this email from my university network manager concerning my computer:
    The computer in question appears to be infected with
    a Trojan or worm that reports home to an IRC server.
    Several examples include sdbot, spybot, gaobot, polybot,
    and some variants of OptixPro. We notice these because
    the computer is trying to connect to a known IRC bot
    controller.
    We often are unable to tell exactly which version of
    which IRC bot an infected computer has, but the
    detection method is rarely wrong. There are hundreds if
    not thousands of known variants of each of the above
    viruses, with new ones being released daily. Updated
    AntiVirus software may or may not detect this threat.
    Odds are good that the attacker obtained the
    password database for this computer, containing all
    of the passwords for all accounts on the computer.
    It is IMPERATIVE that all passwords for all accounts
    on this computer be changed before this computer
    is placed back onto the network.
    Computers infected with an IRC bot should have their
    hard disk formatted and have the Operating System
    reinstalled and patched before coming back onto the
    network. All passwords on the rebuild system should
    be different than they were on the infected system.
    IRC bots not only often come bundled with
    other malicious software, but once they connect to
    the IRC controller, they often download and install
    even more malicious software, without the knowledge
    and/or consent of the computer user. Therefore,
    even if AntiVirus software detects and removes the
    IRC bot, typically more malicious software is left
    behind, still running.
    IRC bots are updated frequently. Even up-to-date
    AntiVirus software often doesn't detect the latest
    IRC bots. Once the AntiVirus companies start
    detecting a particular IRC bot, the bot is typically
    instructed to update itself to a variant that is
    not detected by AntiVirus.
    Because of the above activities, scanning for viruses
    with an AntiVirus product is typically not an effective
    remedy for an IRC bot infection.
    I have symantec antivirus for mac, is there any way I can use it to scan the bootcamp partition? I think I know where the infected file is, but symantec says it's clean. I also have Symantec for Windows.
    It would be a HUGE inconvenience to reinstall windows XP because my disc is at home and I will not be home for another 2 and a half months. Can you give me any tips on how to remove this virus without reinstalling windows XP?
    Thanks,
    Sam

    If you delete it you are only getting rid of half the problem, and likely will be unable to do this.
    Start up in Safe mode.. (If you're having trouble doing this press start and search for MSCONFIG go to boot.ini and start in safe mode).
    This will only run basic stuff for windows and should potentially stop the Winlog running.
    However as I said winlog will probably re-appear because the trojan will likely just retrieve it back from the internet.
    I say the best solution is...
    Restart your mac into OS X, download Avast free edition and Spybot S&D or similar, and ZoneAlarm Firewall.
    Put them on your bootcamp drive. restart into windows in safe mode. Install those and restart back into safe mode if needed.
    Set avast to run a boot time scan (Scans before you load into Windows. Run SpyBot S&D. And set Zonealarm to have atleast some sort of protection running all the time.

  • How I stopped the dreaded "Mooing" sound on my MacBook. (possible solution)

    So I am probably not the last one on this forum to find the dreaded mooing sound on their brand new laptop!
    Yes, I do love my Macbook and it's quite and upgrade from the 15" PowerBook that I came from,(better screen, faster),.. but the day I received the laptop, I had this "moo" sound start. Initially, I thought it was someone snoring in my apparentment, but I can hear it again and again everyday in a quite room..
    So I tried and tried many things to make the moo sound stop..
    * Slowing down the processor by running it as "Better battery life"
    * Unpluggin the AC adapter and lowering the screen res.
    All to no avail. As you can see with my computer, it will probably run a bit hotter since the 7200rpm drive is in there.
    Noneoftheless, I went to Apple store and asked the genius bar in the flagship store in SF about it and they knew about the problem, but could not give me a definitive answer to fix it.
    So, this is what I tried...
    Opened up PhoneBooth (yes, the built-in) iChat program and started up the recording mode so it would trace every movement of me. Then the mooing almost stopped, if not stopped totally.
    I am currently running on AC Adapter with power settings set to "Better Performance" and the mooing has almost stopped. (I say almost since it only moos 1 time every min)
    Hope this may work until Apple releases some sort of fix to resolve this..
    Please post your results here..
    Cheers,
    Wilson

    I was not aware of the fact one could use ringtones as alarms, this will suffice! Although I foresee some very awkward times as the sound does not stop once I respond to the reminder (it keeps going for good five - ten seconds after I "stop" the reminder), but it's better than missing it altogether!
    Thank you very much!
    Regarding the Alarmed app, doesn't it have to be running to actually remind you?
    -Modular747: I don't know anyone who actually reads the terms of service agreement, those things are usually up to thirty, small print pages full of legal jargon. Rules, I do read - not the legal documents (also they often contradict the laws in my country, but that's a whole different story).
    I agree with you - the average customer support consultant mostly cares about keeping his job and earning his salary (don't we all?) and thus racking up completted tasks (i.e. getting rid of customers as fast as possible - in a good mood). The "threat" none the less is real, if a cell phone causes me more trouble than it is worth, I will indeed throw it away (I have done so before) - and recommend a different brand to anyone willing to listen.
    Don't get me wrong, I love Apple and I've been faithfully using and recommending their producs for twenty years now, not because of fanboyism, but because they earned it. This calendar issue, however, is like a toaster that doesn't automatically eject the toast at the set time. I see it as a major flaw and after googling around a bit I see that it's been around since at least 2007 (THAT'S SEVEN YEARS!!) so I strongly believe they are aware of this problem by now, but are choosing to ignore it for some mysterious reason and it really ****** me off.
    I will send the feedback but based on my observations I suspect the Send button is merely a cleverly disguised Delete button.

  • Macbook pro virus?

    Every time i click somewhere it opens a new tap with advertisement. For example when i go to youtube and click on a video or even to write something a new tab opens. Last time 6 new tabs appeared to me, what can i do to stop that? Do i have virus on my macbook?

    Helpful Links Regarding Malware Problems
    If you are having an immediate problem with ads popping up see The Safe Mac » Adware Removal Guide and AdwareMedic.
    Open Safari, select Preferences from the Safari menu. Click on Extensions icon in the toolbar. Disable all Extensions. If this stops your problem, then re-enable them one by one until the problem returns. Now remove that extension as it is causing the problem.
    The following comes from user stevejobsfan0123. I have made minor changes to adapt to this presentation.
    Fix Some Browser Pop-ups That Take Over Safari.
    Common pop-ups include a message saying the government has seized your computer and you must pay to have it released (often called "Moneypak"), or a phony message saying that your computer has been infected, and you need to call a tech support number (sometimes claiming to be Apple) to get it resolved. First, understand that these pop-ups are not caused by a virus and your computer has not been affected. This "hijack" is limited to your web browser. Also understand that these messages are scams, so do not pay any money, call the listed number, or provide any personal information. This article will outline the solution to dismiss the pop-up.
    Quit Safari
    Usually, these pop-ups will not go away by either clicking "OK" or "Cancel." Furthermore, several menus in the menu bar may become disabled and show in gray, including the option to quit Safari. You will likely have to force quit Safari. To do this, press Command + option + esc, select Safari, and press Force Quit.
    Relaunch Safari
    If you relaunch Safari, the page will reopen. To prevent this from happening, hold down the 'Shift' key while opening Safari. This will prevent windows from the last time Safari was running from reopening.
    This will not work in all cases. The shift key must be held at the right time, and in some cases, even if done correctly, the window reappears. In these circumstances, after force quitting Safari, turn off Wi-Fi or disconnect Ethernet, depending on how you connect to the Internet. Then relaunch Safari normally. It will try to reload the malicious webpage, but without a connection, it won't be able to. Navigate away from that page by entering a different URL, i.e. www.apple.com, and trying to load it. Now you can reconnect to the Internet, and the page you entered will appear rather than the malicious one.

    From user Joe Bailey comes this equally useful advice:
    The facts are:
    1. There is no anti-malware software that can detect 100% of the malware out there.
    2. There is no anti-malware that can detect everything targeting the Mac.
    3. The very best way to prevent the most attacks is for you as the user to be aware that
         the most successful malware attacks rely on very sophisticated social engineering
         techniques preying on human avarice, ****, and fear.
    4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
        your computer is intended to entice you to install their malware thinking it is a
        protection against malware.
    5. Some of the anti-malware products on the market are worse than the malware
        from which they purport to protect you.
    6. Be cautious where you go on the internet.
    7. Only download anything from sites you know are safe.
    8. Avoid links you receive in email, always be suspicious even if you get something
        you think is from a friend, but you were not expecting.
    9. If there is any question in your mind, then assume it is malware.
