Trojan horse TR/Spy.Banker.cnq

[Nail]

Ciao a tutti vi contatto per il seguente problema: il mio antivirus(Antivir)continua a rilevarmi il virus
TR/Spy.Banker.cnq. È un Trojan horse e appare solo quando sono connesso a internet nella cartella Temp di Windows con un numero seriale che cambia ogni volta che dopo averlo cancellato si reinstalla (Esempio 3958160295.exe). Nonostante continui ad eliminarlo il virus si ripresenta subito subito dopo pochi minuti. Cosa posso fare per debellarlo un volta per tutte?
Grazie
Ciao

ed elimina l'intera cartella Multi_Media_Italy con KillBox

Ho eliminato l'intera cartella "Multi_Media_Italy" con l'applicativo che mi hai segnalato ma il problema persiste.
Cos'altro posso fare?
Grazie

Folders to delete:
