Virscans.dat and virscan7.dat files

I have a dell lapton 2650 Inspiron XP SP2 windows firewall ON with Norton Internet Security and AntiVirus 2006 with 116 days remaining on subscription.

 

I have found Norton to have taken over my hard drive.  I weekly search for *.tmp files and delete anything from Norton.  CCAPP has taken over my processer and slows down the machine.  Now I did a search for any file over 8000 Kb and have found virscans.dat and virscan7.dat files.

 

Can I safely delete all virscans.dat and virscan7.dat files from my machine?

 

Thanks
