Il log e pulito, prova a fare una scansione antivirus da questo indirizzo
http://security.symantec.com/default.asp?productid=symhome&langid=it&venid=sym

Se ci sono virus, disattiva il ripristino di configurazione, riavvia in modalità provvisoria e fai una scansione antivirus, poi ripeti la scansione on line.
