HT1338 software anti-virus

I have a virus in my MacBook Pro.
I can't open my Facebook account because this virus may take my passwords
how can i solve this problem? Thanks.

It's very unlikely that you have any kind of malware, and more unlikely still that malware would be interfering with your ability to log in to Facebook. Can you be more specific about what the precise behavior you're seeing is?
Is Facebook preventing you from logging in and claiming that you have a virus? If so, see:
Facebook isn’t letting me log in and is telling me I have a virus!

Is anti virus necessary for iMac? if so, what is the best software?

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 simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. OS X security is based on user input. Never click through any request for authorization without thinking.
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. XProtect, Gatekeeper, and MRT reduce the risk of malware attack, but they're not absolute protection. 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, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious 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. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. 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 "zero-day" 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.

HT1338 What anti-virus software shall I use for my Mac OS X 10.6.8?

What anti-virus software shall I use for my Mac OS X 10.6.8?

There are many forms of ‘Malware’ that can affect a computer system, of which ‘a virus’ is but one type, ‘trojans’ another. Using the strict definition of a computer virus, no viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions. The same is not true of other forms of malware, such as Trojans. Whilst it is a fairly safe bet that your Mac will NOT be infected by a virus, it may have other security-related problem, but more likely a technical problem unrelated to any malware threat.
You may find this User Tip on Viruses, Trojan Detection and Removal, as well as general Internet Security and Privacy, useful: The User Tip seeks to offer guidance on the main security threats and how to avoid them.

I've just downloaded FF 4 beta, do i still need to purchase internet security software & anti-virus software for protection?

I have not renewed my McAfee. i am not sure whether FF 4 beta security protection is good enough. I do internet banking often. do i still need to have other security or anti-virus software?

Firefox is just a web browser, you still need anti-virus, anti-malware and firewall protection.

HT1338 safe anti virus for mac book 10.7.5?

since there's more attacks on mac computers, what is the best anti virus, anti malware program of a mac book?

Welcome to the Apple Support Communities
If you want more information about OS X and malware, see > http://www.reedcorner.net/mmg
We don't recommend an antivirus because most of them are useless, but if you want one, you can install Sophos or ClamXav. You can install the one you want, because both works correctly

Some kinds of the Security software(Anti-virus) always disable in Firefox,why ?

None.

They may not be compatible with firefox - it's most likely an add-on. Or if you could explain further it would help better.

Cisco Jabber for Windows - Anti-Virus Software

Hello,
Cisco Jabber for Windows could not resolve outlook contacts, when a client has installed McAffee Anti-Virus Software.
Is there any documentation available, how to setup a Anti-Virus Software, to get Cisco Jabber for Windows running?
Cisco Jabber for Windows Version 9.2.4 Build 4528
Outlook 2013
Thanks
Alex

this is all what we mention about antivirus; http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/jabber/Windows/9_2/JABW_BK_J6915A59_00_jabber-windows-server-setup/JABW_BK_J6915A59_00_jabber-windows-server-setup_chapter_00.html
Some antivirus or firewall applications, such as Symantec EndPoint Protection, block inbound CDP packets, which disables desk phone video capabilities. You should configure your antivirus or firewall application to allow inbound CDP packets. See the following Symantec technical document for additional details about this issue: Cisco IP Phone version 7970 and Cisco Unified Video Advantage is Blocked by Network Threat Protection.
with that being said; we probably would like to get the jabber process excluded from the antivirus list so that it allows for inbound MAPI communication as that is what is used for quering for the outlook contact.
The only process that ever runs from Jabber for windows is "CiscoJabber.exe" which is located in the following path:
C:\Program Files (x86)\Cisco Systems\Cisco Jabber
i hope this helps.

I have what appears to be a virus on my Mac namely MAL/FAK AV-OQ how can I remove it? I have only discovered after running SOPHOS anti virus software???

I have what appears to be a virus on my mac namely MAL/FAK AV-OQ I only discovered it after installing SOPHOS anti virus software.
I cannot remove it automatically with this software it says it has to be done manually.
Where do I start???
Help req'd urgently

That is Windows malware, and cannot affect your Mac. See:
http://www.sophos.com/en-us/threat-center/threat-analyses/viruses-and-spyware/Ma l~FakeAV-OQ.aspx
It may be attached to an e-mail message or could be something that was copied over from a Windows machine via flash drive or something similar. If it is attached to an e-mail message, simply delete the e-mail. (Do not let Sophos, or any other anti-virus software, quarantine the message or attachment! That can corrupt the mailbox that the message resides in.) If it isn't an e-mail message, you can let Sophos quarantine and delete the file or you can delete it yourself.

My iPhone 4 has crashed. i tunes will not recognize it and I can't restore it. I sync with macbook pro and all software is up to date. no anti-virus applications/software are on my macbook. any ideas?

my iphone 4g has crashed. itunes doesn't seem to recognize it and wil not let me restore it. i have updated all software and there are no anti-virus apps/software on the macbook that this phone syncs with. i do get an error message on the phone that says something like the accessory is not compatible but I have no accessory for the phone other than the apple chargers and ear buds. any thoughts?

The possible fix for the "this accessory is not compatible" is to carefully clean the dock port with isopropyll alcohol especially the pins which are on top of the mid rib. Be firm but do not break anything. Let it dry for a minute. See if that helps, if not try to clean one more time. If problems persist might need to Visit Apple.

I installed 10.6.8 from 10.6.6 on my Macbook Pro and now can't open Safari-think it's something to do with the Intego anti-virus software. Reverted Intego software back to default state and now computer just boots ups up slowly and can't access a thing.

I installed 10.6.8 from 10.6.6 OS on my MacBook Pro and have not been able to open secure sites on Safari. Think it has something to do with the Intego Anti-virus installed. Tried restoring Intego to default status and now my Mac barely boots up and does nothing else but spin. Ugh. Has anyone had similar issues and if so, were you able to resolve? How? Thanks,

1: Backup your user files folders of Documents, Music, Pictures etc., to a external powered drive (not TimeMachine) and disconnect.
2: Insert the 10.6 installer disk and reboot holding c
3: Simply reinstall OS X without erasing the drive, it will overwrite the installed version of OS X and the root level software, but leave your Applications folder contents (expect Apple bundled programs) and user files alone. (but backup anyway in case it fails)
4: Reboot and the Integro is gone out of your system, but there may still be something laying around in Applicaitons to delete. Use Software Update to get up to date.
5: You don't need anti-virus on a Mac, Apple provides it already for you sight unseen.
6: If you Software update, the bad certificate issues are pulled, thus are not a threat.

Anti-Virus Software for Windows Vista Beta 2 Preview-

As many of you with MacBooks and MacBook Pros are already installing Windows Vista Beta 2, you may have forgotten about Anti-Virus/Internet Security software. Microsoft is offering Free Anti-Virus and Internet Security software from it's partners that work with Windows Vista. Here is the link: http://www.microsoft.com/athome/security/viruses/wsc/en-us/windowsvistabeta2.msp x
The Trend Micro looks a bit more promising, as it is their Internet Security Suite, and not just the Ant-Virus, as is from eTrust.
I will be installing this onto one of my Windows Machines soon, and will post back on how they work. Hope this helps anyone installing the Windows Vista Beta Preview 2.

Hi SkipHaughay,
As far as I know Parallels does not support Windows Vista at this time. Vista must be installed over Windows XP on Boot Camp. IF you do install through Boot Camp, I hear that everything works except for sound and wireless I believe. Hope this helps.

Anti-virus software on Windows XP pro sp3 with Virtual PC

Hi,
I'm running Virtual PC 7.0.3 with Windows XP pro Sp3 on eMac. Has anyone found the need to run a anti-virus software etc as part of the Windows system? Or will the firewall on the broadband router modem be sufficient protection?
Many thanks.

Thanks for the reply.
Any recommendations on AV software?
I tried installing a free version of AVG AV but the install would not complete, I ended the process after 1.5 hours.

Are there solutions to Compatibility Issues with Thunderbird, Windows 8.1 and Anti-Virus Software, e.g., MacAfee?

Since I upgraded to Windows 8.1, Thunderbird freezes up and goes into "Not Responding" mode repeatedly every few minutes. My research indicates that it is a problem with compatibility with antivirus software, which obviously is needed with an e-mail program. How can this problem be solved, or is there an antivirus program that works seamlessly with Thunderbird and Windows 8.1?

Personally I use ESET NOD32. It is not cheap, but it is unobtrusive and appears to get the job done. Originally I was drawn there for their server protection, but since I no longer have windows servers that need is gone, but I see no reason to change.
Previously over the years I have used;
* Norton (Found it just to much embedded into the operating system. Something went wrong with it and Windows would not boot.
* Microsoft Security Essentials. Any application using large data files was unworkably slow. That included Thunderbird.
* AVG It was just clunky and I did not like it.
But the big issue these days is the products are not just anti virus, they are suites including firewalls, password managers/vaults and often spam and scam tools. It is usually these later tools that cause the most issues with the firewalls blocking anything but known versions of known software and spam tools that mess up because it has not had enough testing.
Basically your on your own in selecting a product5. I can not recommend one. But I seriously question the need for mail scanning. Especially after that remarkable admission by Symantec regarding Norton's not scanning mail.
Thunderbird does not run any scripts in mail, nor does it do anything with attachments before you open them and then it decodes them and places them in the temp folder where any good anti virus will scan them.
Personally I suggest anti virus rather than security suite software. Especially so if you use Chrome or Firefox browsers and they both use Google lists of known malware and phishing site to block inadvertent visits.
Windows has a firewall, your modem (over 90%) has one as well, those firewalls block ports, protocols and route traffic. Do you also need one that blocks programs?
Mozilla products have a password manager, do you need another? And so the list goes on.
