I just checked on a different machine, and get the same warning:
Virus: 'Troj/Momma-B' detected in C:\temp\delme\vlc-0.4.1-win32.exe
No action taken
This machine was a virgin install of Win2k (I just did the install
yesterday) and has a fresh, untainted (to the best of my knowledge as it
comes fresh from Sophos) Sophos AV installed.
Note that this isn't the VLC binary itself, just the Installer (which is
the Nullsoft NSIS installer, if I'm not mistaken) that's infected with the
Trojan. I'm assuming where-ever it's ultimately packaged is a Win32
machine, and that's where the virus is coming from.
Also note that this is a fairly new Trojan. Sophos announced an IDE for it
on May 21st (so, less than two weeks ago).
