Salve da un pò di tempo riscontro sempre lo stesso problema, ciò nelle cartelle C:\documents and settings\all users\documenti e E:\ si ricreano continuamente i files SETUP.EXE e AUTORUN.INF. Ogni volta Avast riconosce setup.exe come infetto dal trojan Win32:Horst-GV e lo elimina, ma poco dopo ricompare.

Ho già provato a fare di tutto
- ATF Cleaner x ripulire il pc
- scansione più volte con Avast
- Anti spywere: Ewido, Ad-Awere, Spybot search and destroy, CWShredder e Zona Alarm Pro
- Scansione online con Kaspersky Online Scanner

Ma il problema continua a ripresentarsi e come se non bastasse da poco mi si disintalla anche la scheda audio e ogni volta la devo reinstallare. Non so + che fare.. Spero mi possiate aiutare.
