Alright, a friend of mine has been infected with some major virus or something, heh...  Maybe several virii.

He ran AdAware, CWShredder and Spybot Search and Destroy.  He also ran AVG anti-virus and he's gotten rid of most of the infected files and such, however there are still a few that can not be deleted or quarantined.

These files are:
Java/ByteVerify
Trojan Horse Downloader.winshow.l
Trojan Horse Downloader.winshow.L

Does anyone know how to get rid of these without reformatting?  I've done all I know how to do for him but I'm not sure what else...  Anyone?

Thanks, all. :)
