Buon anno a tutti!
Ieri avira si è bloccato mentre stavo facendo una scansione, non riuscivo a chiuderlo e nemmeno spegnere il pc e quindi ho forzato lo spegnimento....
Oggi ho provato con clamwin e si è bloccato anche lui e non rispondeva più nulla e ho dovuto forzare nuovamente per spegnere il pc....ed ora eccomi qui, questo è il log di HijackThis...che c'è che non va?
Per ora non mi azzardo più a fare una scansione, aspetto un vostro consiglio.
Grazie
Simonetta
