Virus on a mac?

I have an iMAC and I just got a message that one of my emails bounced because I had a virus in the attachments. But I created the attachments on this computer and never took them on any other computer. is is even possible that I have a virus? if so what should I do? Ippolita

Hi.
I wouldn't worry too much about that. If your intended recipient was a corporate/company email address, many of these companies have built-in fire walls in their email servers with tons of protection to prevent a virus infection, and often, they have a "list" and this will flag off, or "trigger an alarm" if the email contains certain word or attachments, or even the origin/source of the email (address)
Take my company for example, the email system somehow will bounce back my email if I send an attached Targa format image, I have to zip the file first before I email
Cheers

How do I remove a Blacole virus from my Mac?

My MacKeeper picked up several JS/Blacole and JS/iFrame viruses on my Mac. Any suggestions as to how I remove them? I'm not sure how I got them but they show up every time I run the virus scan, even after quarantining them so I'm assuming I need to delete them somehow. Also....any ideas where I got them?

Not a virus, but it is malware: The Safe Mac » Search Results » adware removal.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
          Mac OS X Snow Leopard and malware detection
          OS X Lion- Protect your Mac from malware
          OS X Mountain Lion- Protect your Mac from malware
          About file quarantine in OS X
If you require anti-virus protection Thomas Reed recommends using Dr.Web Light from the App Store. It's free, and since it's from the App Store, it won't destabilize the system. If you prefer one of the better known commercial products, then Thomas recommends using Sophos.(Thank you to Thomas Reed for these recommendations.) If you already use Sophos, then be aware of this if you are using Mavericks: OS X Mavericks- Sophos Anti-Virus on-access scanner versions 8.0 - 9.1 may cause unexpected restarts
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 anything targeting the Mac because there
     is no Mac malware in the wild, and therefore, no "signatures" to detect.
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.

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.

I've got OSX/Genieo.A virus on my mac and don't know how to get rid of it and why I have it

I've got OSX/Genieo.A virus on my mac and don't know how to get rid of it and w I have it

There is no need to download anything to solve this problem.
You installed the "Genieo" malware. The product is a fraud, and the developer knowingly distributes an uninstaller that doesn't work. I suggest the procedure below to disable Genieo. This procedure may leave a few small files behind, but it will permanently deactivate the malware (as long as you never reinstall it.)
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
Triple-click anywhere in the line below on this page to select it:
/Library/Frameworks/GenieoExtra.framework
Right-click or control-click the line and select
          Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.
If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
A folder should open with an item named "GenieoExtra.framework" selected. Move that item to the Trash. You'll be prompted for your administrator password.
Move each of these items to the Trash in the same way:
/Applications/Genieo.app
/Applications/Reset Search.app
/Applications/Uninstall Genieo.app
/Library/LaunchAgents/com.genieo.completer.update.plist
/Library/LaunchAgents/com.genieo.engine.plist
/Library/LaunchAgents/com.genieoinnovation.macextension.plist
/Library/LaunchDaemons/com.genieoinnovation.macextension.client.plist
/Library/PrivilegedHelperTools/com.genieoinnovation.macextension.client
/usr/lib/libgenkit.dylib
/usr/lib/libgenkitsa.dylib
/usr/lib/libimckit.dylib
/usr/lib/libimckitsa.dylib
~/Library/Application Support/com.genieoinnovation.Installer
~/Library/LaunchAgents/com.genieo.completer.download.plist
~/Library/LaunchAgents/com.genieo.completer.update.plist
If there are other items with a name that includes "Genieo" or "genieo" alongside any of those listed above, move them as well. Some of these items will 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.
Restart and empty the Trash. Don't try to empty the Trash until you have restarted.
Step 2
From the Safari menu bar, select
          Safari ▹ Preferences... ▹ Extensions
Uninstall any extensions you don't know you need, including ones called "Genieo" or "Omnibar," and any that have the word "Spigot" or "InstallMac" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
Your web browser(s) should now be working, and you should be able to reset the home page and search engine. If not, stop here and post your results.
Make sure you don't repeat the mistake that led you to install this trojan. Chances are you got it 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 has 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 youever download a file that isn't obviously what you expected, delete it immediately.
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.
Finally, be forewarned that when Genieo is mentioned on this site, the attacker sometimes shows up under the name "Genieo support." He will tell you to run a fake "uninstaller." As he intends, the uninstaller does not completely remove the malware, and is in fact malware itself.

How do I get rid of viruses on my mac?

Hi,
I have ran a speed test on my internet connection and it is currently at 0.48, I believe that I may have a virus in my mac. I have had a technician from my provider test the line and the speed on his laptop was 8.45.
What is the best free program that I can get? Or do I have to fork out money for an antivirus program?
thanks

Are you using WI-FI? If you are, option-click on the Airport icon. What is the Transmit Rate showing there?
To enter new DNS numbers (Sys Prefs>Network>Advanced) click on the + button. You will get a new field in blue, as shown in the screenshot below. Enter one number there, then hit OK. You will be brought back to the main tab. Hit Apply. Go back to Advanced and repeat for the second number, then hit OK. You will be brought back to the main page and hit Apply again. You can reorder the way the numbers appear by dragging them. Not absolutely certain of this, but the numbers first listed will be the DNS servers used first; second will be contacted next. If you put all those numbers in (all three sets), you can then test which servers are the fastest for you by rearranging the list order.
DNS (Domain Name Server) is like the phone book. It translates names into telephone numbers. You can't dial a name. DNS servers translate site names into numbers. Some servers are better/faster than others.
Also be sure to turn off IPv6 in TCP/IP

If I use Bootcamp, can I get Windows viruses on my Mac?

I am using Mac OS X 10.8.3. I am about to install Windows 7 on my iMac with Bootcamp. Can I get Windows virus on my Mac because of Bootcamp?

If you do, it'll only affect the Windows partition of your hard drive.
If you feel really worried, I'd suggest running Windows in a virtual machine using Parallels or similar. You can set things up so that there's no access to your Mac from the virtual machine and, if the VM gets a problem, you can just delete it.

Best virus software for mac OS 10.5.8?

What is best software for mac OS

VIRUSES
No viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions.
It is possible, however, to pass on a Windows virus to another Windows user, for example through an email attachment. To prevent this all you need is the free anti-virus utility ClamXav, which you can download for Tiger and Leopard (check with them about Lion) from:
http://www.clamxav.com/
The new version for Snow Leopard is available here:
http://www.clamxav.com/index.php?page=v2beta
Note: ClamAV adds a new user group to your Mac. That makes it a little more difficult to remove than some apps. You’ll find an uninstaller link in ClamXav’s FAQ page online.
If you are already using ClamXav: please ensure that you have installed all recent Apple Security Updates and that your version of ClamXav is the latest available.
Do not install Norton Anti-Virus on a Mac as it can seriously damage your operating system. Norton Anti-Virus is not compatible with Apple OS X.
FAKE ANTI-VIRUS SOFTWARE and associated MALWARE
Do not be tricked by 'scareware' that tempts computer users to download fake anti-virus software that may itself be malware.
Fake anti-virus software that infect PCs with malicious code are a growing threat, according to a study by Google. Its analysis of 240m web pages over 13 months showed that fake anti-virus programs accounted for 15% of all malicious software.
Scammers trick people into downloading programs by convincing them that their PC is infected with a virus.
Once installed, the software may steal data or force people to make a payment to register the fake product.
Beware of PDF files from unknown sources. A security firm announced that by its counting, malicious Reader documents made up 80% of all exploits at the end of 2009.:
http://www.computerworld.com/s/article/9157438/in which Rogue_PDFs_account_for_80_of_all_exploits_says_researcher
TROJANS and RE-DIRECTION TO FAKE WEBSITES
The appearance of Trojans and other malware that can possibly infect a Mac seems to be growing, but is a completely different issue to viruses.
If you allow a Trojan to be installed, the user's DNS records can be modified, redirecting incoming internet traffic through the attacker's servers, where it can be hijacked and injected with malicious websites and pornographic advertisements. The trojan also installs a watchdog process that ensures the victim's (that's you!) DNS records stay modified on a minute-by-minute basis.
You can read more about how, for example, the OSX/DNSChanger Trojan works (by falsely suggesting extra codecs are required for Quicktime) here:
http://www.f-secure.com/v-descs/trojan_osx_dnschanger.shtml
SecureMac has introduced a free Trojan Detection Tool for Mac OS X. It's available here:
http://macscan.securemac.com/
First update the MacScan malware definitions before scanning. You can also contact their support team for any additional support - [email protected] [/b]
The DNSChanger Removal Tool detects and removes spyware targeting Mac OS X and allows users to check to see if the trojan has been installed on their computer; if it has, the software helps to identify and remove the offending file. After a system reboot, the users' DNS records will be repaired.
(Note that a 30 day trial version of MacScan can be downloaded free of charge from:
http://macscan.securemac.com/buy/
and this can perform a complete scan of your entire hard disk. After 30 days free trial the cost is $29.99. The full version permits you to scan selected files and folders only, as well as the entire hard disk. It will detect (and delete if you ask it to) all 'tracker cookies' that switch you to web sites you did not want to go to.)

What is the best Anti Virus Software for MAC?

Is Norton still number one, or does anyone recommend a more reliable and efficient software?

The facetious (but largely true) answer, lemacman, is OSX.
I've yet to see any virus checker that doesn't cause far more trouble than viruses do on Macs running under OSX.
Nortons / SAM AV was , mostly, the best under OS's up to OS9. That doesn't mean that it didn't cause problems, but it was generally better than the others. I used it briefly under OSX until one of the updates did something nasty (deleting all of my email, from memory) .
Virex became popular in some quarters for a while but unfortunately at one stage had the unfortunate habit of making peopl's processors run at 100% , causing overheating and other problems in iMac G5s and the like. If I had a quid for every occasion I had to tell someone to remove Virex at that time I'd be a financial rival to Donald Trump!
etc etc etc.
If you really feel you HAVE to have a virus checker, the only one I'd even consider at present is the free ClamX AV . There is a bit of a problem in that you have to use the public beta version if you are running Snow Leopard, but I have little doubt that even a public beta of it will cause less hassles than the current releases of the various commercial offerings!
So - given the number of Mac OSX affecting viruses "out in the wild" at present (none) - the safest course is not to use any, but if you really feel as insecure using your Mac without one as walking down the street without your pants on, then my vote would be that you go for the public beta of ClamX AV.

My ip adress was attacked by a bot virus,therefore my mac screen has been blurred as if the ink is poured on the surface,I want a solution to fix it?

My ip adress was attacked by a bot virus,therefore my mac screen has been blurred as if the ink is poured on the surface,I want a solution to fix it?

First of all, this sound like a very unlikely set of symptoms for a virus of any kind. Lets try a test to see if you actually have a hardware issue.
Boot the MacBook Pro to it's recovery partition by holding down the command and R keys during startup. Is the screen issue still there? If that is the case, you have a problem with the MBP's hardware and need a repair.
Contact Apple using expresslane.apple.com if you are in a country that supports it or call the appropriate phone number on this page. Alternatively carry the MacBook Pro in to an Apple retail store or service provider to ask for an estimate.

Virus software for mac

Which is the recommended virus and malware scan software for Macs

This is another many-months-old topic. It's generally not helpful to pull old posts like this out of the archives and reply to them, as you've been doing today. The issue is already settled, one way or another.
As for BitDefender, it hasn't tested very well, and I wouldn't recommend it. See:

Question about virus on a mac

ive read posts about people saying that macs cant get virus's. but i was mainly jus wondering what would happen if u downloded something off limewire or the internet and it had a virus in it would it affect your mac? or because its a pc virus nothing would happen.Do pc virus's affect macs even if one got on your mac.thanx for any replies.

Kappy,
I have to respectfully disagree with a couple of your comments:
Most users are behind routers whose built-in firewalls provide sufficient protection against outside invasion. Furthermore, hackers are not interested in your computer or mine. They are only interested in computers that have something worth getting.
Here's why:
1. Although the percentage is rising, most consumers are not behind routers. A very large number of broadband consumers are directly connected to a cable or DSL modem.
2. The overwhelming majority of consumer-grade routers, and especially wireless routers, are not configured for security. They tend to have two common features:
- Default (wide open) settings configured.
- Default or NO admin passwords.
3. Any Joe Sixpack's computer can be used to crack a "worthwhile" computer's data, send spam, collect email addresses, distribute illegal content, and for DOS attacks. Botnets are extremely profitable.
Cracking a router and using its CPU and limited memory for spam and DOS is becoming more common as well. It's important to protect your router, too.
That said, I find the rest of your comments, especially the "If it bleeds, it leads." attitude in the press, fair.
-Wayne

Anti-virus on the Mac

Anti-viruses on the Mac system seem to be a very controversial topic. In my opinion, every computer should have protection but I'd like to know from other Apple IT Specialists like myself what is your opinion on this? If you feel we should have protection on our Macs, what is the best program out there? I've been using Symantec and haven't had any problems with it but I've seen on many threads that many others don't like to use it.

OS X has got its own security systems, as XProtect and Gatekeeper, that makes your Mac safer, so I think that you don't have to worry about antiviruses that can slow down your computer or damage OS X. See > http://www.thesafemac.com/mmg
Anyway, if you want an antivirus, you can install ClamXav or Sophos, but they are designed to detect Windows virus more than OS X ones (if there are any)

Question: Do I need to run and anti virus program with MAC OSX Lion? Have heard different opinions! If so what would you recommend? Was looking at Sophos. Does anyone have any experience with this? Thanks

Do I need to run and anti virus program with MAC OSX Lion? Have heard different opinions!
You will continue to hear different opinions here, where thoughts range everywhere between "anti-virus software is the evil spawn of Satan" to "anyone not running anti-virus software is a fool."
Truth is, this is still a very personal decision on a Mac. Depending on circumstances, it is still very easily possible to stay safe without using anti-virus software, but circumstances and personal preferences vary widely. Besides which, anti-virus software cannot even remotely provide you a guarantee of protection!
To learn how to stay safe (with or without anti-virus software), and how to decide whether to use anti-virus software, see my Mac Malware Guide.
