trojanski konj help!!!

No torej na očetovem službenim računalniku se je pojavu trojanski konj z imenom Win32/TrojanDownloader.Agent.NQV.No Pc sm inštaliral Nod32 in mi javi da je trojanc povezan z datoteko winlogon.exe.Sedaj pa nevem kako to rešt da ne bi slučajno zjebal pc-ja ker je na njem kar dosti podatkov.

Verjetno je povezano s tem trojancem še to da se IE čudno odziva,meče čudne strani vn in dela kar sam v nekem Ful screen načinu(brez ikon)v orodni vrstici pa javlja nek da je pc ogrožen,ker nima antivirusnega.,in na začetku je metalo na neko stran od diskclenarja 2006.
zdej to ne dela več .mogoče še bo .

V programu hijackthis mi je vrglo ven to

No, tud meni se je za vikend en trojanc naselil na abakus. Mal sem po netu iskal in najdu Sdfix. Sem sledil navodilom in je stvar porihtal. NOD32 mi ne javlja več trojanca. Zanima me kaj je ta sdfix? KAKo da to porihta stvar, en nod32 pa nč ne more, pa adaware tud ni nč najdu, pa windefender tud ne.
