Ciao a tutti, è la prima volta che invio una richiesta di "aiuto" e pertanto vi prego di perdonarmi eventuali svarioni che faccio.

Il problema è questo:

da qualche tempo sul mio notebook Acer Aspire 5672 - S.O. Win XP - l'antivirus installato (Avast) mi segnala la presenza del rootkit MBR\.\\..PHISICALDRIVE0.
Avast consiglia di riavviare il sistema e di fare una scansione all'avvio.

Dopo aver effettuato la scansione sia in modalità normale che provvisoria, il problema si ripete.

Nonostante non abbia rilevato perdite di dati o altro, tuttavia non riesco ad utilizzare Internet Explorer.

Ho fatto il log con Hijack che allego, ma non ci ho capito molto.

Mi potete aiutare, per favore?

Ho notato cmq che il mio problema è abbastanza diffuso.
