In essence, open the Terminal utility (in the /Applications/Utilities/ folder) and run the following commands (copy one line at a time, followed by press Enter in the Terminal after it is pasted):


defaults read ~/.MacOSX/environment DYLD_INSERT_LIBRARIES

defaults read /Applications/Safari.app/Contents/Info LSEnvironment

defaults read /Applications/Firefox.app/Contents/Info LSEnvironment


ls -la ~/../Shared/.*.so


ls -la ~/../Shared/.*.dyld


ls -la ~/Library/LaunchAgents


When finished, press Command-A to select all the contents of the Terminal and paste it to a message on this board, and we will let you know if your system has any suspect files that are associated with the malware, and how to proceed from there.


Alternatively, you can download Sophos Home Edition (http://www.sophos.com/en-us/products/free-tools/sophos-antivirus-for-mac-home-ed ition.aspx) or ClamXav (http://www.clamxav.com), update their definitions, and then scan your system to find known variants of the malware.

Thank you for this advice. Probably no issues, but followed your instructions and sent you this. Can you help?:

Hi, I'm almost positive I have a virus on my macbook that is not allowing any of my browsers to connect to the internet. I know this because I tried to diagnose it on the network side by speaking with my internet provider, and after trying several things, they concluded that it's some setting that's in my browser. My airport shows that I'm connected to wifi, but when I get onto Google Chrome, the page shows up as "Unable to connect to the Internet" Error 106. I followed the instructions above to see if I have the flashback virus, and below is what I got. Can you please help?

If your Mac was infected you would have gotten a message it was removed. No news is good news.

There NO viruses that attack Macs and fairly little malware.


"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."

Those tests are difficult for a novice to use properly. In fact, you've mis-typed several of them, is most of your results are meaningless.


Just run Software Update if you haven't already. And for more information about Flashback, see:


http://www.reedcorner.net/about-the-flashback-malware/


The symptoms you describe are not typical of Flashback anyway. I'd advise you to post your own topic with a clear description of the symptoms for assistance with fixing the problem.

You're going to need to post a question on a new topic. This one is a year only, and the malware we were discussing at that time is gone.


What you need to do is start a new question of your own, then describe in words what the problem is. Do not make the assumption that your problem is caused by malware (it probably isn't)... Just describe the symptoms and let the experts here propose solutions.
