Salve a tutti.
Il mio PC è molto rallentato, non regge più di tre finestre di IE e, controllando col Task manager le Prestazioni della CPU, ho visto che è molto "occupata", tanto che, anche quando non supera il 10%, appaiono i led rossi...
Ho fatto tutte le scansioni antivirus e malware.
Ho riconfigurato il sistema eliminando tutti i servizi inutili. Niente da fare.
Non mi rimane che copiarvi il file Log di hijackthis, sperando che qualcuno possa venirne a capo e/o che non si sia rotta la CPU.
Questo è il file:
