    You may have installed the "VSearch" trojan, perhaps under a different name. Remove it as follows.

    This trojan is distributed on illegal websites that traffic in pirated content. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect much worse to happen in the future.
    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 this Internet criminal 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.

  • I am trying to open iTunes on my mac. But a box pops up saying "The folder iTunes is on a locked disk or you do not have write permissions for this folder". Anyone know what that means? I've had my computer 2 years and its never had a problem opening it

    I am trying to open iTunes on my mac. But a box pops up saying "The folder iTunes is on a locked disk or you do not have write permissions for this folder". Anyone know what that means? I've had my computer 2 years and its never had a problem opening it

    I've already right-clicked on the application, clicked "get info", and changed it so all people listed in the "Sharing & Permissions" section have the "read & write" privilage.
    The error message is referring to your iTunes library, not your iTunes application.
    You need to check and fix the permissions of the iTunes folder in your iTunes library. This is by default located in your "Music" folder.
    Select the folder Music > iTunes  in the Finder, right click on it or Ctrl Click and click "Get Info". At the bottom of the contextual window thatwill  pop up, disclose the Sharing and Permissions brick, change your status from Read only to Read & Write. You may need to click the padlock icon to make changes.

    If the reset doesn't work:
    FORCE IPAD INTO RECOVERY MODE
    1. Turn off iPad
    2. Turn on computer and launch iTune (make sure you have the latest version of iTune)
    3. Plug USB cable into computer's USB port
    4. Hold Home button down and plug the other end of cable into docking port. Do not release button until you see picture of iTune and plug (very important)
    5. Release Home button.
    ON COMPUTER
    6. iTune has detected iPad in recovery mode. You must restore this iPad before it can be used with iTune.

    It's probably the MacDefender scareware trojan horse. If you have this here is how to remove it.
    1. Open Activity Monitor look for MacDefender process double click on it and hit quit or force quit.
    2. Go to System Preferences, Go to accounts, Go to login items look for anything related to MacDefender hightlight it by clcking on it once. Then hit the minus sign to remove it.
    3. Go to applications folder and drag MacDefender to the trash.
    4. Open finder and do a search for Macdefender and remove anything you see related to MacDefender.
    5. Open Spotlight (the little magnyfing glass in the menubar far right corner) and do a search for MacDefender.
    6. Restart your computer and empty trash.
    7. If you feel you need to have virus protection for your Mac use ClamXav. It's the recommended AV program for MacOSX. Hope this helps.

  • How can I stop pop-ups saying "There is a problem logging on to server...You do not have permission..."., How can I stop pop-ups saying "There is a problem logging on to server...You do not have permission...".

    I have a Mac Mini (early 2009) running OSX 10.8.1 on a Windows network that is driving me nuts.
    Background
    Typically, 6 or 7 computers are running (Windows 7, OSX 10.8.1 and Linux) on the network at any given point in time.   Network printers and hand helds (iphones, PlayBooks, etc.) are also connected.
    The problem
    If one specific Windows 7 desktop is running, a pop-up error message comes up frequently.  The eror message is: 
    There was a problem connecting to the server "[Server name or IP]".    You do not have permission to access this server.
    The pop-up sometimes refers to the device name and sometimes refers to the IP address of the desktop.
    Oddities:
    This does not occur on a MacBook Pro also running 10.8.1
    The error message does not occur for other Windows computers on the network.  I have laptops running Windows 7 Professional that have never shown up on the error message..
    Files on the problem desktop are easily accessible through [Finder].
    Things I've tried to resolve the problem:
    Ran software update - multiple times
    Changed the destination drive for [Time Machine] and completed a backup
    Cleared the "Recent Server" list from the [Finder][Go][Connect to Server] screen
    Attempted to demount the desktop in [Finder].  The option was not available
    Disconnected from the desktop in [Finder].  This did not resolve the problem and the desktop was automatically showing on the [Shared] list in [Finder] after the next reboot.
    Booted in SAFE mode to see if the problem re-occurred in SAFE mode.  It did not.
    Any suggestions would be appreciated. 

    Thank you.  It wasn't in there directly, but CISCO's "Network Magic" was there.  Removing it appears to have solved the problem.
    Thanks again and have a good weekend.

    hello, such problems are usually caused by adware on your pc. please go to ''firefox > addons > extensions'' & remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc). also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there and do a full scan of your system with the security software that you have in place and different other tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner].

  • I keep gettin updates from my app store but yet when I go in and update all it starts the update and then pops up and tells me that the application cannot be downloaded at this time. I have had to delete a few apps bc this isn't working.

    I keep getting updates from my app store but yet when I go in and update it starts the process but then a message pops up that says the download cannot be done at this time. I have had to delete a few apps because of this. I have also signed out and signed back into my account and turned my phone on and off and still does the same thing. Help!

    Hi tmcrae
    First check that your device is not full, maybe you may have to delete some photos or apps to make space to do updates. if its not full then you will have to try pluging it into your pc/mac running itunes then doing a backup and restore. Then you should be able to do your updates.
    Sorry but i cant think of any other way if its showing as installed already but is not there.
    Hope that helps

    hello i am trying to help a friend to get the update for the mac os x maverick and msg pops up saying distribution file not verified

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Boot in safe mode and log in to the account with the problem. 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. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually login 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.
    Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • I have a Mac running OS X 10.6.8 and have installed all updates and disabled Java Applets.  Do I need to put virus protection on this computer and, if so, any recommendations?

    I have a Mac running OS X 10.6.8 and have installed all updates and have disabled Java Applets.  Do I need to install antivirus software and, if so, do you have a recommendation on what works best.

    Mac OS X versions 10.6.7 and later have built-in detection of known Mac malware in downloaded files. The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders. In most cases, there’s no benefit from any other automated protection against malware.
    The most effective defense against malware is your own intelligence. All known malware that affects a fully-updated installation of Mac OS X 10.6 or later takes the form of trojans, which can only work if the victim is duped into running them. If you're smarter than the malware attacker thinks you are, you won't be duped. That means, primarily, that you never install software from an untrustworthy source. How do you know a source is untrustworthy?
    Any website that prompts you to install a “codec,” “plug-in,” or “certificate” that comes from that same site, or an unknown site, merely in order to use the site, 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.
    “Cracked” versions of commercial software downloaded from a bittorrent are likely to be infected.
    Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
    Disable Java (not JavaScript) in your web browser(s). Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in Mac OS X 10.5.8 or earlier, because Java in those versions has bugs that make it unsafe to use on the Internet. Those bugs will probably never be fixed, because those older operating systems are no longer being maintained by Apple. Migrate to a newer version of the Mac OS as soon as you can.
    Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
    Never install any commercial "anti-virus" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use ClamXav — nothing else.

    I've recently upgraded to Lightroom5.7.1 and now when I try to import photos a window pops up saying 'the photos can't be imported 'cos the files can't be read'. I had no problems before upgrading. I have Windows8 & can't find any 'app' which sets the type of files I can import. Any help appreciated.

    Well, think about it. This is a Lightroom forum. We are here to answer questions about Lightroom and how to solve problems in Lightroom. Your permissions issue is an operating system issue, not a Lightroom issue. I didn't mean to be sarcastic. But there are plenty of Internet resources that will answer that question.
    I just went to Google and typed in "change disk permissions", and there are links for the Mac as well as for Windows listed. There's no sense in me rewriting instructions that are already available.

  • Everytime I try to use FF, dozens of pop ups come up saying FF wants to use various Fuji and Fusi fonts. Nothing I do seems to stop these popups and it takes me 10 minutes before I can use FF. why does this happen; how can I stop it.

    The specific message runs something like this: Firefox wants to use Fuji Extended Bod Italic on the volume WD startup. It is not installed. Allow Firefox to use it?
    I can choose allow or don't and there is a checkbox that says "do not ask me again." no combination of these options stops the progression of pop ups, which can last for minutes and will start all over again next time I start firefox.

    Among the alternatives not mentioned... Using a TiVo DVR, rather than the X1; a Roamio Plus or Pro would solve both the concern over the quality of the DVR, as well as providing the MoCA bridge capability the poster so desperately wanted the X1 DVR to provide. (Although the TiVo's support only MoCA 1.1.) Just get a third-party MoCA adapter for the distant location. Why the hang-up on having a device provided by Comcast? This seems especially ironic given the opinions expressed regarding payments over time to Comcast. If a MoCA 2.0 bridge was the requirement, they don't exist outside providers. So couldn't the poster have simply requested a replacement XB3 from the local office and configured it down to only providing MoCA bridging -- and perhaps as a wireless access point? Comcast would bill him the monthly rate for the extra device, but such is the state of MoCA 2.0. Much of the OP sounds like frustration over devices providing capabilities the poster *thinks* they should have.

    You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
    Back up all data before making any changes.
    One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
    If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
    Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
    Malware is also found on websites that traffic in pirated content such as video. 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. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
    In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere  should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
    Still in System Preferences, open the App Store or Software Update pane and check the box marked
              Install system data files and security updates (OS X 10.10 or later)
    or
              Download updates automatically (OS X 10.9 or earlier)
    if it's not already checked.

    "Avast" is the worst of the whole wretched lot of commercial "security" products for the Mac. Not only does it fail to protect you from any real danger, it may send personal data (such as web browsing history and the contents of email messages) back to the developer without your knowledge, give false warnings, destabilize and slow down the computer, expose you to network attack, and corrupt the network settings and the permissions of files in your home folder. Removing it may not repair all the damage.
    Some versions of the product also inject advertising into web pages. In short, apart from the fine print in the license agreement, Avast is indistinguishable from malware, and is arguably worse than any known malware now in circulation.
    Back up all data, then remove Avast according to the developer's instructions. Restart.
    If you tried to remove Avast by dragging an application to the Trash, you'll have to reinstall it and then follow the instructions linked above.

  • Mac air start up,then pop-up yahoo mail screen, and ask me type password..how can i cancel it

    Mac air start up,then pop-up yahoo mail screen, and ask me type password..how can i cancel it

    Ok, finally I figure it out!!
    You need to give computer access to the password of Yahoo.com
    You go to the application "Key Chain" that is included in your MacBook Pro.
    Then you go to the first tab that should say something with "Login/Session" and you should see all your saved passwords.
    Scroll down to the saved password of  "Yahoo: your-username @ ...
    Click on it, you should see a window opening
    Go to the tab "Access Control"
    Then click on "Allow all applications to connect .. ", NOT the option "Ask every time for allowance" or you can also just add the program "MAIL" with the "+" icon !!
    There you go, now you should not have to worry again !!!!!!
    (this step copy form someone posted)
    Anyway can fixed it!!!!!

  • Is there a way that iTunes can act as a Radio Alarm Clock? I have found the radio station I enjoy listening to in the iTunes Radio List. Is there anyway iTunes (and my Mac) can be set to come-on and start playing that Radio Station from Sleep mode at spec

    Is there a way that iTunes can act as a Radio Alarm Clock?
    I have found the radio station I enjoy listening to in the iTunes Radio List. Is there anyway iTunes (and my Mac) can be set to come-on from Sleep mode and start playing that Radio Station at specific times of the day?
    Any App or plug-in that does that?
    Many thanks
    Kevin

    Turning your Mac into a clock radio.
    1.  In iTunes create a playlist that contains just the radio station you want to wake up to.
    2.  Export the playlist (as .m3u works well).  Get Info on your playlist file and look at the Open With entry to make sure it points to iTunes, VLC or some other app that will stream your station.
    3.  In iCal create an event entry at the time you want to wake up.
    4.  Right (or Control) click on your wakeup event and select Get Info.
    5.  For "alarm" select Open File.
    6.  Now under Open File there will be a place to add the file to open.  It will probably be some default entry (like iCal).  Click on it will allow you to select "other."  Then use the file dialog to select your playlist file.
    Your Mac will wake you up at the appointed time.  You don't need to keep iCal running.  If you want to put you Mac to sleep for the night then there is one more thing you need to do.  Open System Preferences to Energy Saver and click on the Schedule button.  Check Start up or wake and set the wake up time to slightly before your iCal alarm time.
