ci sono un po di righe da fixare stando all analisi online,ma io non me la sento di dare consigli in tal senso,essendo facile fare danni anche gravi,quindi ti consiglio di fare una scansione completa con questo:
http://software.aiutamici.com/software?ID=80346
lo scarichi,lo aggiorni e fai la scansione completa.se trova qualcosa posta il log.
al posto tuo farei anche una scansione in provvisoria con il tuo a.v.
ciao.
