Win32: Trojan-gen {VC} help/info

I am having a problem with finding information on this Win32: Trojan-gen {VC} file that I received a “warning” for today. Here’s the message I received:

ACCOUNT: NT AUTHORITY\SYSTEM
APPLICATION: 1892
DESCRIPTION: Sign of “Win32: Trojan-gen. {VC}” has been found in “D:\WINDOWS\autoload.exe” file.

Just two weeks ago I also received 4 warnings for Signs of “Win32: Trojan-gens. {UPX!}” but those were expendable files so I just deleted them. What does the upx! versus the VC labeling mean? ???

Finally, I did a scan with McAfee online just now and surprisingly they didn’t flag the file in question. And unfortunately they found two others that Avast! has yet to warn me about. :frowning:

I’m not certain what to do regarding the Trojan-gen {VC} file…I just noticed that it’s not in my windows folder and is currently in the avast infected files chest. Could somebody please shed a little light for me on this matter? I can’t seem to find much information regarding this trojan…and the information that I have discovered is inconsistant to say the least. Any help would be VERY much appreciated…thanks :wink:

I’m running Windows XP Media Center Edition

There are many threads already about this. I suggest you first do a search on the forum before starting a new one. I think you find this one (as one of the many) providing you with the answer to your little problem:

The labeling “VC, UPX, …” doesn’t mean much - it’s just a tag narrowing the trojan type somehow (UPX would be packed by UPX, VC probably means it was written in Visual C). It’s not possible to say more from the “generic” Trojan-gen name. You can submit the file from the Virus Chest to ALWIL Software and ask about these specific ones.
