Invasion of the incomple file
 

I am fairly new to OS 10. Running a new to me but used dual 867 G4 mirror drive.
There is a sticky data file in the incomplete box.
It can't be trashed and it reinvents itself with the current time evey time it is trashed.
Lime wire does not seem to be functioning properly and the incomple files can't be deleted. Each time I get close to getting rid of the incomplete files a 100 more pop up.
Is this a virus?
Should I reload Limewire.
Any help appreciated.
Thanks Mike

The msg that pops up is Swapfile 2 is infected with hacktool .underhand and cannot be repaired.
Will this do serious damage to files? Is there an Antivirus program out there that will deal with virus. This one seems particulary nasty to get rid of. Anyone had experience with this one?
