Buongiorno... ho un problema quasi identico ad un'altra persona che ha postato qui... ma non ho trovato alcuna risposta...
Ciò che mi si apre è una schermata con scrito:

Critical Error!

Attention, "il mio nome"! Some dangerous viruses detected in your system. Microsoft Windows XP files corrupted. This may lead to the destruction of important files in C:\WINDOWS. Download protection software now!
Click OK to download the antispyware. (Reccommended)

...e questo succede praticamente quasi ogni volta che apro qualcosa...
dopo ciò mi si apre una pagina web... QUASIASI cosa io clicchi:

http://free-viruscan.com/id/4912933/4/1/

E il file (sicuramente fasullo) che mi dice di scaricare è:

ie-av.exe

Proveniente dal sito:

http://getieantivirus.com




Ho letto cmq la procedura consigliata
ed il log di HijackThis è:
