Ho sicuramente un virus di tipo trojan. Ho esaminato il log di hijackthis che allego e trovo solo queste due cose strane:
F2 - REG:system.ini: Shell=explorer.exe
O4 - HKCU\..\Run: [WinMedia] C:\361101032253072.exe
Se fixo lo 04 e rifaccio lo scan immediatamente ricompare.
Una successiva ricerca sul disco non trova nessun punto exe con quel nome, ma ricompare.
Qualcuno mi può aiutare? Grazie.
