Aiuto! virus introvabile e irrimovibile

[fran2]

Improvvisamente norton antivirus ha smesso di funzionare. Ho provato a rinstallarlo inutilmente.
Ho installato AVG che non ha rilevato nessun virus, Kaspersky che ha rilevato e rimosso alcuni virus, ma il problema persiste.
Norton non si installa, alcuni programmi in esucuzione automatica vengono resi inutilizzabili e il pc è lento.
Ho provato a fare scansioni on-line senza alcun risultato.
Cosa fare?
