E' roba di oggi, e non capisco cosa sia e come poter non farlo accadere.
In pratica: AVAST mi riconosce un malware e mi avvisa con la solita cartella sonora in pop-up.
Quello che vien fuori è
Nome file
C:\DOCUME~1\Donati\IMPOST~1\Temp\25267468.exe\[UPX]
Nome malware
Win32:Downloader-AO [Trj]
Tipo malware
Cavallo di troia
versione VPS
0638-0, 19/09/2006
Poi il solito sposta/cancella/rinomina, al che faccio cancella. Opziono cancella definitivamente, e poi mi compare la finestrella di Windows (quella con il cerchio rosso e la x bianca), dicendo "Impossibile eliminare il file C:\DOCUME~1\Donati\IMPOST~1\Temp\25267468.exe\ e bla-bla-bla sul fatto che no riesce a trovare quell'applicazione".
Applicazione che non ho, andando a cercarla. Tutta questa trafila comparirà sistematicamente ogni 5-10 minuti, sia che usi il pc sia che non lo usi, sia che sia connesso o no, e via dicendo.
Che roba è? Come lo elimino? Come risolvo?
Allego, nel caso servisse, responso hijack
