KIS 2006 ga je pronasao kod mene u Program files, u virustlist.com nema informacija o njemu. Upravo skeniram ceo komp, pa vam javim da li ga je KIS sredio ili ne.

U prvom momentu, KIS samo mi je registrovao prisustvo trojanca, da bi ga u ponovljenom skeniranju pronalazio i brisao. Ne bih se toliko ni trudio oko njega da sam ga nasao na viruslistu i da ga nisam pronasao na 20 i kusur mesta u racunaru.

Najverovatnije ima zastitni mehanizam koji pravi novu kopiju pri pokusaju brisanja stare.
Injektovao se u neki od aktivnih procesa (winlogon, explorer...) i odatle pravi kopije samog sebe.
Jesi li probao skeniranje RAM-a, pa da vidis da li ti KIS nalazi da je negde injektovan?

Nemam KIS pa neznam kako se opcija tacno zove. U KAV 5.x se ide na Scan Objects, pa tu ima da se stiklira skeniranje memorije.
Ako to ne pomogne, imas u Uputstvima uputstvo za HijackThis, postavi ovde log pa da vidimo da li mozemo nesto rucno da odradimo.

Jel 82.208.201.4 stvarno tvoj DNS?
Jesi li sam instalirao Advanced JPEG compressor?

Sto se ostalih stavki tice, ne vidim nista neobicno.
Uradi jos nesto, cisto da budemo sigurni:
- napravi poseban folder za HijackThis, ali ga nazovi nekim levim imenom, da ne asocira na HijackThis
- preimenuj HijackThis.exe u nesto tipa HT4.exe
- napravi novi log i postavi ga ovde

Ovim cemo biti sigurni da nemamo posla sa nekim procesom koji se skriva od procesa programa HijackThis.

Ovako. 82.208.201.4 bi trebalo da jeste moj DNS, tako bar pise u protokolu TCP/IP. Jesam, sam sam instalirao Advanced JPEG compressor (ne pitaj me otkud mi)


Na desktopu sam napravio folder, i dao mu ime bobby, i u njega iskopirao HijackThis, preimenovao ga u ht4 i evo rezultata skeniranja:
