the repair function is not implemented for Win32:Vitro... try DrWeb CureIt (but there's no guarantee to get it all back)..

is your OS 32bit or 64bit? the update for 32bit virut was released yesterday, but the update for the 64bit version will come later...

Hm, since when these two differ? I though as far as scan engine is concerned, there are no changes between 32bit and 64bit. But now i see that 64bit seems to always lag behind :-\

it's just the case of Virut (the only widespread virus, which has a 64bit variant and needs a special algorithmic detection)... as you probably know the x64 assembler is different from x86 assembler and that makes also the detection approach slightly different (maybe a bit harder to keep the track).. there's already a detection of 64bit virut (Win64:Virtob), but it must be updated to cover the few newest variants...

In that case i understand it. I thought it's just Win32 version of this virus.
