Ciao scusate se posto nuovamente la mia richiesta ma su suggerimento di un amico ho effettuato anche un log con il programma hijackthis e lo riporto di sotto.
Quando accendo il pc norton antivirus mi indica che nel computer ho : backdoor.trojan e in windows/systems32/icqchk.exe.
Ho seguito le vostre istruzioni:
ho attivato la modalità provvisoria e ho fatto una scansione completa con norton e con ad adward ma non mi ha segnalato niente.
Poi ho riavviato e mi ha di nuovo segnalato il trojan.
Poi sono passato nella modalità normale.
Ho scaricato hijackthis e vi indico di seguito il log:
