Win32: Virut

My comodo av can not detect the Win32: Virut virus!
I have lots of infected files on my pc and the cav say nothing
Any help?

You can try with COMODO Boclean Anti-malware:

Virut is in his segnature.

Well, I have Boclean installed, Comodo Firewall and Comodo Anti Virus … and nothing happens!

Perhaps it is a new variant.
How did you discover that it is “Virut”?

Btw, try downloading Hijackthis (all 2 versions):

Make a log with all 2 version and encloses two log files to the post (not to publish the log, but only attach files).

ok, I’ll do that, but I send a zip file to comodo labs for testing with a Virut (as avg) infected exe program

Yes, You can also use CAVS to send the file directly.

See below … file 80x26.exe (25.600 bytes) is infected by Virut but nothing is reported

According to CA,this is a polymorphic virus of some sophistication.With CAVS still being beta and lacking advanced detection techniques,it’s not surprising if it evades detection.


I was told to attach the log in a file and not to post the log.
And even using all two Hijackthis.

BTW, these 5 elements should be fixed:

Why do you have this file 80x26.exe here:
G:\Documents and Settings\XXXXX\Desktop\Virut\80x26.exe

and where it was first to move there?

Can you submit that file to and post here the log?

You should also download Spybot - Search & Destroy and make an update and scan your disk:

I would use the Spybot S&D helloween version. You can find it here :

Although it is still a Beta, it has some bug fixes the official 1.5 release lacks.

I was told to attach the log not malware!

Please do not ever attached malware in the post, can be dangerous for inexperienced users.

We must try to solve problems rather than create them! :-\

File will be sent to the COMODO Laboratory.
