problem with trojan (created by herss.exe)

[astralreb]

Hello, my computer is infected by a trojan. A process called herss.exe is running and it creates cvasds0.dll.I ve already made two full scans with mbam and quite a few scans with an antivirus but the process isnt killed yet.

I submit the mbam and hijack logs (my mbam log was in greek so i translated it to english)

Thank you in advance

Hi,

This one is a flashdrive infection, so it makes sense that, whenever you insert the infected flashdrive or other removable media, that it will install again.

In either way, above HijackThislog doesn't show any traces of this worm anymore... so can you scan one more time again with malwarebytes and post the new log in your next reply?
