Trojan.PWS.Wsgame
Worm.Sifiliz (DRWEB classification)
Opening my flash drive with Total Commander I found a read-only system file mvxm.cmd and similiarly attributed autorun.inf . These files weren’t shown in Windows explorer, regardless of the setting to see hidden-system files. I’ve already come across trojans that write such files to root directories, so I immediately performed a checkup. Avast didn’t find anything. And then I checked root dirs of all local drives to discover the same situation there. Clearly malware activity- so I downloaded Drweb CUREIT (Drweb.ru) scanner and used it. Cureit found Trojan.PWS.Wsgame, and additionaly a Worm.Sifiliz in a html file on my harddrive. Sad that avast ignores the trojan (which thanks God is for stealing passwords for online games, which I dont play), and the worm (which as I found has appeared in 2007, see http://www.antivirus.ru/VirAnaliz71024.html if you can read Russian), some antiviruses have improved, here are the results of VIRUSTOTAL.COM scan:

So now six antiviruses recognise it instead of 2, in a half-year’s time, but avast isn’t among them. Alas.
AVAST version: 4.8, WIN XP SP2 and further updates.
I placed the malware RAR-packed here if anyone wants to check them:
