Ovo su objasnjenja za pomenute fajlove..
Sad, pominjes dva AV programa.. Koliko znam to nije dobro..
Odluci se za 1 (jedan) od ta dva AV programa ili uzmi neki treci, uradi UPDATE baze i preskeniraj u SAFE MODE windowsa i daj nam report sta si uradio da ti mozemo dalje pomoci..
Pored AV programa preskeniraj i neki adware programom, SpyBot S&D..
Pozdrav.
