Packed.Hacktool -- unable to delete...

Hi there. Norton found a .exe on my girlfriend's computer the other
day. When I clicked on the name I was taken to the following URL on
symantec's site:

Note that I was unable to delete it and it didn't pull up on a search
of the system either. Symantec says "Packed.Hacktool is a generic
detection for hacktool programs that have been processed with software
packers." I'm not sure what that means.

Should we be doing anything or is it harmless?
