Posted 17 March 2009 - 12:06 PM

I have discovered that ONE of the infections is, in fact, Win32/Tanotos.M. I have been able to successfully identify it and clean it using Grisoft's rmtanat.exe tool found here: <hxxp://www.avg.com/filedir/util/avg_rem_sup.dir/rmtanat/rmtanat.exe>

I still have the issues of registry changes that inhibit RegEdit, TaskMan, etc.


I support several PCs at an organization that have become infected with what appears to me to be several different malware packages. I have sifted through what I could find on www.bleepingcomputer.com as well as general Internet searches and have had no success in cleaning these machines up.

All of these PCs have been running Grisoft VG 7.5 - 8.0 for quite some time now without event. Whatever has infected these machines was not detected by AVG unitl it was too late. AVG reports many *.exe files as infected with either Win32/Heur and\or Win32/Tanatos.M. I understand that Win32/Heur generically means that the detection is really non-specific and was flagged by hueristics rules.

Further scanning with Dr. Web Cure It! reports Win32/Sality infections. However, scanning with the AVG Sality removal tool identifies no infected files.

Thanks in advance everyone. I greatly appreciate your time devoted to helping each other. It's an invaluable resource.

As per guidelines, I am pasting in DDS.scr results below:
