ciao ,
con hijackthis fixa queste due voci :
O4 - HKLM\..\Run: [Winphx service] pdzvcf.exe
O4 - HKLM\..\RunServices: [Winphx service] pdzvcf.exe

e dopo esserti assicurato di avere accesso a file e cartelle nascosti , cerca ed elimina:
C:\WINDOWS\System32\<b>pdzvcf.exe</b>

Aggiorna il tuo sistema , compreso ServicePack2 e Internet Explorer
