...prima di tutto grazie mille per il tuo aiuto....

ti posto il nuovo log, nn ho trovato delle cose che mi avevi scritto ma tutto quello che mi hai detto lo ho fatto...

i problemi credo sia difficile risorverli del tutto perchè mi sono sparite delle finzioni di windows e credo vadino reistallate dal cd....

grazie ancora per l'aiuto ....
un ultima domanda, proma di cambiare pc avevo come antivirus avast...ora mi hanno consigliato avg ma nn mi sembra molto buono....tu che mi consigli....

Meglio sarebbe stato continuare il primo thread, così perdo il filo del discorso.
Comunque devi fixare con la modalità che conosci le seguenti righe:

---

O4 - HKLM\..\Run: [lphcpa5j0ec19] C:\WINDOWS\system32\lphcpa5j0ec19.exe
O4 - HKCU\..\Run: [strsrv] C:\WINDOWS\system32\hkpyxeja.exe

---

poi cerca ed elimina i seguenti file in rosso:
____________________________________
C:\WINDOWS\system32\lphcpa5j0ec19.exe
C:\WINDOWS\system32\hkpyxeja.exe
____________________________________

AVG 8 e da preferirsi ad Avast!. Questa è la mia opinione.
Ciao.
