If AVG confirmed that the above filenames are infected, you should get rid of it soon.

Seems that the filename that you mentioned are positive as infected files. Again, if AVG confirmed that those are infected files, delete them ASAP.
I just installed and ran AVG free version anti virus on a win 2000 machine, got some interesting results,
2 viruses were found and moved to "virus vault," but the files listed below were all found twice, i.e., they were in the winnt/system 32 folder and in a subfolder under that.
so should I just delete them? thanks - fj
