trojan horse downloader Keenval.B

[pepsisteve]

I am running Windows XP home.
I have the free AVG program.
This message keeps popping up periodically on my screen:

"Trogan Horse Downloader, Keenval.B
is found in file C:\System Volume
Please remove this virus, please run AVG for Windows"

The first time that I ran AVG for this problem, it "healed" it.
Now when I run the AVG scan it says that everything is clean.
Any help would be appreciated.

thanks MicroBell for the quick reply.....I cleared the sys. restore [volume] folder....everything is running fine. I realize now that I probably posted in the wrong forum..sorry about that.....thanks again, steve
