Hi,
This evening, while executing my weekly light scan (I run a deeper one on Sunday), I got this virus alert :
avast! [REZ-DE-CHAUSSEE] : Fichier "C:\Documents and Settings\Admin\Mes documents\Arrivages\Installés\Images\virtualdubmod_virtualdubmod_1.5.10.1_francais_45486.exe" est infecté par "Win32:Adware-gen [Adw]" virus.
"_ Mon analyse légère" tâche utilisée
The mentioned file is the installation program of the french version of virtualdub (or an add-on to localize it).
This is a well known video program.
What's more surprising is the fact that it has been present for months on my disk, without any warning till today !
I'm not sure it's possible to post files somewhere, in case someone would like to analyse it more thoroughly - in any case I wouldn't post without having being invited to do so.
I doubt it contains really a virus - but I don't use this program, I've just run it a few times just after installation, to see what it can do, and never again since this moment.
