Just ran the "defaults read /Applications/Safari.app/Contents/Info LSEnvironment" script in the Terminal Window and it return "File Does Not Exist"

I guess my iMAC is clean then - right?

That definitely is a plus. You now have to run

Code:

defaults read ~/.MacOSX/environment DYLD_INSERT_LIBRARIES

in Terminal. If you get another error, you are all clear.

There is however talk that the trojan installs into your default browser however so I'm not too sure on how that goes, you can perhaps do some more reading around. I haven't bothered because I'm pretty sure I am clean.

Thanks so much.

Wonder where this magical figure of over 600,000 infected machines comes from originally? Doubt that I would trust a Russian AV software company!

I was wondering this too. How do they tell/know that 600k computers are infected?

I downloaded the sophos program that OSXdaily suggested.

Lo and behold…I am now "safe" from 3.5 million separate "threats" per their claims.

I had no idea Macs were so insecure.

My friend installed Sophos and his computer is noticeably slower.

It's very likely bogus. Read Randy Singer's latest post to the Anti Virus Sticky thread.

Yeah I just tried it out to see what it looked like. Turned off. Come on, protection from 3 1/2 million Mac viruses.

LOL.

So it is now in the trash.

Hi

The thing to remember about Sophos is that so far I think it is only Mac compatible Anti VIrus software to look for both Mac and PC viruses/malware.

This should help make sure that your Mac does not become a carrier for PC viruses and malware.

I know that since the beginning of this year it has found about three PC related viruses that came in through one of me email IMAP services into a bulk/spam mail folder.

Enabling me to track them down and get rid of them.

Hope this helps a little
