Compromised WMV files in P2P networks

Several potentially dangerous WMV (video files) are currently floating around P2P networks. If downloaded and opened, these files will direct computers to infected web resources instead of the safe ones named in the original video files. The infected web resources have downloadable malware: adware and Trojans.

We are detecting the compromised WMV files as Trojan-Downloader.WMA.Wimad.a and Trojan-Downloader.WMA.Wimad.b.
