Trova e cancella i file in rosso:
C:\WINDOWS\kiasys.dll
C:\PROGRA~1\MYWEBS~1\bar\1.bin\mwsoemon.exe

Scarica VIRIT :
http://www.tgsoft.it/italy/download.htm lo aggiorni (cliccando sulla parabola in alto) e lo fai girare in Modalità Provvisoria (è molto importante).

Scarica Spy-Bot da qui http://www.aiutaamici.com/software?ID=10831 e fai una scansione sempre in Modalità Provvisoria.



Riavvia il computer.
Devi controllare alcune chiavi del registro:
Clicca su Start - Esegui - e digita "Regedit", arriverai all'editor del registro.
Nella sottochiave
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
cancella, nel pannello di destra, il valore (in rosso)

"Shell" = "Explorer.exe, msmsgs.exe"
Nella sottochiave

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
Cancella, sempre nel pannello di destra

"MSN Messenger" = "%System%\msmsgs.exe"

Nella sottochiave

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion
cancella

"uuid" = "[random characters]" (nomi casuali)

Nella sottochiave

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\policies\explorer\Run

cancella

"notepad.exe" = "msmsgs.exe"

Esci dall'editor del registro, e posta un log di hijackThis
