What about the Mac Virus

Will a real Mac user tell me about the latest virus? The Media has several different versions

Adobe is aware of malware posing as its Flash Player and warns users to ignore any updates that didn't originate on its own servers. "Do not download Flash Player from a site other than adobe.com," said David Lenoe, Adobe's product security program manager, in an entry on Adobe Product Security Incident Response Team's PSIRT blog. "This goes for any piece of software (Reader, Windows Media Player, QuickTime, etc). If you get a notice to update, it's not a bad idea to go directly to the site of the software vendor and download the update directly from the source. If the download is from an unfamiliar URL or an IP address, you should be suspicious."
The ‘Flashback Trojan’:
A version of an existing Trojan Horse posing as a legitimate Flash Player installer (named “Flashback.A” by a security firm) is designed to disable updates to the default Mac OS X anti-malware protection system, potentially leaving the system open to the manual installation of other malware without any system warnings. The latest Macs do not have Plash Player included. In order to prevent a potential infection with “Flashback” Trojans, Mac users should always obtain their copy of Adobe Flash Player directly from Adobe’s official website and to disable the "Open 'safe' files after downloading" option in Apple's Safari browser to avoid automatically running files downloaded from the Internet. Also, do not turn on Java in Safari Preferences/Security. Few websites use Java. Javascript is something entirely different and should be left active.

What about the Mac OS 9.2 from Mac OS X

Do you think I can install Mac OS 9.2 directly from the second Mac OSX CD on a PowerBook 3400c with 2gb HD and 80MB of RAM?
I'm asking because my friend got rid of his Mac and gave me his Mac OS X CD's and since, I know I can't install X on my machine, maybe the 9.2 would do...
Or would that require Mac OS 9 helper?

Hi, Prosis. I suspect the CDs given to you will be of no value at all with your PB 3400. No retail (universal) OS X installer disc set includes an installer for OS 9. The only Mac OS X installer CD sets that include installers for OS 9.x are model-specific installers, and none of them is specific to a PB 3400. I think it very unlikely that you will be able to start your computer up from any CD in such a set. Even if you're able to do so, I doubt very much that an OS 9 installer designed for some other Mac model will install a functional OS 9.0.x or 9.1 — let alone OS 9.2.2, which is unsupported on your computer.
OS 9 Helper is only useful for applying the OS 9.2.1 and 9.2.2 downloadable updaters to an already-installed OS 9.1. It does not make possible any other method of installing any version of OS 9 from any source disc.
There is no way to install a bootable OS 9.2.2 directly from any CD on any Mac, except from an installer CD that is specific to that Mac model and was originally shipped with it.

The Macintosh (with Appleu2019s Mac OSX) is not supported for crystalreports.com as Microsoft Internet Explorer (IE) is the only browser we officially support and IE is not available on the modern Macintosh. Having said this, my experiences are positive with both Safari and Firefox when accessing crystalreports.com. I recommend Firefox, having found it to be more compatible with our crystalreports.com features. Alternatively, you could run Parallels Desktop for Mac (http://www.parallels.com) with a Windows XP or Windows Vista VM enabling you to use IE version 6 or IE version 7.

HT1338 what about the problems with the trojan virus is that a problem for my mac as well?

What about the problems with the Trojan virus will this be a problem also for me using Mac

What Trojan?
If you're referring to the DNS Changer Trojan, it's highly unlikely you're affected. The actual distribution of the trojan was stopped several years ago and the perpertrators jailed.
The FBI has been maintaining the servers used by the trojan for the last 5 years in order to give affected systems time to be purged. They will finally shut them down on Monday.
Ensure that your router and the Mac's network settings are set for the DNS addresses of your ISP, or if you're not sure what they should be, change them to Open DNS using the IP addresses;

What is the best virus protection for a Mac?

What is the best virus protection for a Mac?

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 actually been tested by Apple (unless it comes from the Mac App Store), 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. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe.
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 evade Apple's controls.
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. How do you know whether a source 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 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.
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, Java on the Web is 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. In Safari, this is done by unchecking the box marked Enable Java in the Security tab of the preferences dialog.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a specific task, enable Java only when needed for the task and disable it immediately when done. Close all other browser windows and tabs, and don't visit any other sites while Java is active. Never enable Java on a public web page that carries third-party advertising. Use it, when necessary, 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 they get a false sense of security from it, and then they may behave in ways 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.

First you do NOT I repeat DO NOT have a virus, currently there are no virus's for OS X. This means you do not need antivirus software, if you insist on installing antivirus software then I'd recommend ClamXav. You have what is called a Trojan, the primary difference between the two is the user has to give permission for a Trojan to download and install itself. The one you got is going around right now however the good news it's quite easy to get rid of. Please read the following article for instructions.

What is the preferred virus scan program for iphone? I believe that I have a virus. My phone will come on by itself and it appears to be recording audio. I have read about spyware/surveilance viruses that will record audio and take photos.

My phone is not jailbroken. I don't know what you mean about hacked. Maybe it is hacked? This is what is happening: About three times over the past few months I've noticed that my phone while "off" will come on (light up) and the screen shows an arrow towards the bottom; an arrow such that you would see on various "players" in order to "play" video or audio, I've searched my phone and cannot find any app that produces this particular screen though. Once I pick up the phone when this screen myseriously appears out of nowhere and press anything, it goes away and goes to the standard "slider" front page to unlock the phone.

What should I know about the recent virus on apple products?

To Whom can best help,
I recently learned about the recent virus that infected more than 500000 computers. I heard many talk about the software apple uses as the safest software available. However, now that I own a few products from apple, this recent virus that got ahold of some personal information has me wondering what is the best route to protect cell phones, ipods, ipads, and macbooks? is there an AV recomended? It would be great to get some adivce from apple techies. I tried looking up some information on the recent problem that had happened, I was hoping it would be addressed on the primary page of apple but found it wasn't. I am just a little paranoid about people accessing my info and try my best to stay ahead of the virus/trojans and stuff. for these electronics are there any really really amazing security apps people would recommend?
sincerely, a concerned customer

First, it's not a virus but a trojan. We mostly recommend ClamXav 2.2.4 as anti-virus software for OS X.
Two Helpful Links Regarding Flashback Trojan
A link to a great User Tip about the trojan: Flashback Trojan User Tip
A related link in the tip to a checker: Malware Checker Dowload Link
A Google search can reveal a variety of alternatives on how the remove the trojan should your computer get infected. This can get you started.
The trojan attachs through Java. If you don't have Java installed then you won't be affected. Java is not installed with Lion.

Try using ClamXav 2.2.4. If you are not now using a hardware router I highly recommend you do so. Preferably use Ethernet for your local network. If you use wireless be sure it's protected by using WPA2 security.
Use your head and don't download something when you don't know what it is, what it does, or where it's from. Stay off of unknown websites and don't click links if you think you're not sure what will happen.

Hi,
i'm a new member of this community. I've recently learn about flashback malware and other threats to Mac devices. I've installed the new Mac OS X update for Lion 10.7, and the flashback removal tool. What about the update for Flash Player? Should i install it? Otherwise, should i permanently remove this app?
I realy need some advice.
Thank's to all.

Be sure to install the latest version of Safari (version 5.1.7) which is available via Software Update (in the Apple menu) if you have not already installed it. This update will automatically disable older versions of Flash when new versions are available, and will instruct you on how to install the latest version on your system. This should help keep your system safe from any vulnerabilities in Flash.
Note that this is only useful if you use Safari, though other browsers have their own update mechanisms you should research and enable or configure to your liking.

What is the recommended virus software for my apple laptop?

What is the recomended virus protection software for my apple laptop?

OS X already includes everything it needs to protect itself from viruses and malware. Keep it updated with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Disable Java in Safari > Preferences > Security.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgement, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

With ransomeware becoming a threat, what is the best virus protection?

With ransomeware becoming a threat, what is the best virus protection? I am running OS-X Yosemite and want to protect against virus intrusion. What are the best approaches, including what virus protection software?

Ransomware and viruses are unrelated to one another, so your question is logically inconsistent. To learn about "ransomware" read "Ransomware" web pages.
What are the best approaches, including what virus protection software?
The best approach to Internet security does not rely upon any third party virus protection, for the reasons that follow.
There will always be threats to your information security associated with using any Internet - connected communications tool:
You can mitigate those threats by following commonsense practices
Delegating that responsibility to software is an ineffective defense
Assuming that any product will protect you from those threats is a hazardous attitude that is likely to result in neglecting point #1 above.
OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "clean up", "speed up", "optimize", "boost" or "accelerate" your Mac; to "wash" it, "tune" it, or to make it "shiny". Those claims are absurd.Such products are very aggressively marketed. They are all scams.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources.
Illegally obtained software is almost certain to contain malware.
"Questionable sources" include but are not limited to spontaneously appearing web pages or popups, download hosting sites such as C net dot com, Softonic dot com, Soft pedia dot com, Download dot com, Mac Update dot com, or any other site whose revenue is primarily derived from junk product advertisements.
If you need to install software that isn't available from the Mac App Store, obtain it only from legitimate sources authorized by the software's developer.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iCloud, iTunes, or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Java can be disabled in System Preferences.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
The same precaution applies to Adobe Flash Player. Newly discovered Flash vulnerabilities appear almost weekly.
Beware spontaneous popups: Safari menu > Preferences > Security > check "Block popup windows".
Popup windows are useful and required for some websites, but unsolicited popups are commonly used to deceive people into installing unwanted software they would never intentionally install.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever receive a popup window indicating that your Mac is infected with some ick or that you won some prize, it is 100% fraudulent. Ignore it.
The same goes for a spontaneously appearing dialog insisting that you upgrade your video player right this instant. Such popups are frequently associated with sites that promise to deliver "free" movies or other copyrighted content that is not normally "free".
The more insistent it is that you upgrade or install something, the more likely it is to be a scam. Close the window or tab and forget it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. Most of these attempts are pathetic and are easily recognized, but that hasn't stopped prominent public figures from recently succumbing to this age-old scam.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.

Very Important, how much Free Space is on your Hard Drive first of all? Click on the Macintosh HD on the Desktop, then do a Get Info on it.
First, Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if things work OK in Safe Mode.
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
In the Memory tab, are there a lot of Pageouts?
