Ragazzi ho un file che si mette in
c:\windows\temp\pioc1.exe

Gli antivirus non me lo trovano,
ho appena pulito il pc (post) ma nulla di fatto.

Ogni tanto appare e mi butta giù la connessione ADSL tentando di creare un'altra connessione.
Lo rimuovo dai file in RUN dal registro, ma poi riparte.
Oltre tutto non riesco a killare il processo, nemmeno con i programmi della sysinternal

Allego hijack log
