Trojan.Brisv.A is a Trojan horse that infects media files which may cause Windows Media Player to access a malicious URL.
The Trojan horse searches the compromised computer for .asf, .mp2, .mp3, .wma and .wmv files, which it then infects. When opened in Windows Media Player the infected files cause the program to connect to a malicious URL which may result in more malware being downloaded on to the compromised computer.
Infected media files may be downloaded on to the computer through file-sharing programs.
Files infected with Trojan.Brisv.A are detected as
