W32/SALITY.L

[tommyn]

salve,
il mio pc è stato infetto dal un W32/SALITY.L che antivir rileva in continuazione senza dare tregua. Ho effettuato anche altre scansioni, ma il vuris non viene eliminato del tutto.
Come eliminarlo?

Devi darci i nomi dei file infetti, magari anche vediamo un log della scansione di hijackthis o di combofix.
