HEUR-DBLEXT/crypted

[Scarymiss]

Salve a tutti, avrei un problemino con un virus che mi sta facendo andare di matto. L'antivirus (AV Guard) ha trovato questo HEUR-DBLEXT/crypted, il quale fa comparire spesso una finestra di pubblicità sul desktop. Per quanto lo metta in quarantena ogni tot secondi l'antivirus si rifà vivo segnalando il file infetto.
Qualcuno saprebbe aiutarmi? ringrazio in anticipo e allego anche una scansione di HijackThis. (lo trascrivo dato che mi dà errore nel caricamento)

I processi sospetti:

C:\found.000\dir0043.chk\SpybotSD.exe

Le voci sospette:

N.B.: Quelli in grassetto non sono sicuro ma le directory in cui risiedono sono molto sospette...
