negli ultimi giorni ho subito diversi attacchi che sono comparsi sotto diverse forme:
popup di finti antivirus (l'ultimo di antivirus 2010)
scritte sul desktop : your computer is infected!..
difficoltà a usare i browser
processi che partono e intasano la cpu

prima ho provato la rimozione manuale essendo un neofita.
poi ho iniziato a cercare online e ho seguito la vostra guida.
quindi ho usato ccleaner, spybot, malwarebytes, windows malicious software removal, tdsskiller (perchè l'ultimo virus individuato era alureon.h)
ogni scansione mi rivela e toglie qualcosa ma continuano sempre a ricomparire.
vi ringrazio anticipatamente per l'aiuto e
vi allego il log di hijackthis
