Infected AVI file? Win32:Agent-AHMG [Trj]

Had an old AVI file that has been on my system for years…Never caused any problems as far as I can tell. Always been a fairly meticilous scanner. Nothing has ever detected this trojan in this avi file.

Any ideas on the issue of an AVI file being infected with Win32:Agent-AHMG?

Had the latest AVG set to maximum scan depth.

The file is from 2007 - and it’s about 700Meg - too big for the free-bee multiscanner site.

And rather than scrapping the whole file, because I am a more or less full time Linux user, who does not have to live with the endless problems that Microsoft brings, I also have some EXCELLENT text editing programs, that I can hack into the file with and delete / cripple the trojan with.

Any ideas on WHAT to look for and HOW to find it?

How does Win32:Agent-AHMG translate into code? What do the headers look like? what is the signature of it? Etc.?

impossible to say from your info…

only way to tell is to upload the file to www.virustotal.com and test with 40+ malware scanners

The max upload for virustotal is 32MB I believe, it could be even less. No just checked, 32MB max upload.
