ciao a tutti,
ho un portatile di un'amica nel quale AVG trova un trojan "downloader..." (non ho presente il nome esatto.
Non riesco ad andare in modalità provvisoria, schiaccio esc F2 F12 ma ogni tasto mi porta al menù del bios e F8 non fa nulla.

Abbiamo fatto una scansione con hijack, eccola, mi sapete dire qualcosa?
grazie e ciao

Ciao, il log è pulito da spyware
esegui queste operazioni

Fai una scansione antivirus on line da questo indirizzo
http://security.symantec.com/sscv6/default.asp?productid=globalsites&langid=it&venid=sym
se la scansione on line rileva dei virus significa che il tuo antivirus è stato infettato o non è in grado di risolvere il problema, ti consiglio di formattare il disco fisso e reinstallare tutto, altrimenti prosegui

Nel sistema non é presente un Firewall, installa questo programma se non ne utilizzi già uno
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=56
e disattiva l'inutile firewall di XP, leggi qui
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=160&SH=N

Alcuni portatili hanno un tasto speciale per entrare in modalità provvisoria, leggi il manuiale del portatile.
