Record Number Of Viruses, Trojans Etc. On A PC?

I will like to know from the Cnet uses that use windows xp sp2 to tell me how many viruses that they has on their pc. My record number is 105 viruses when doing a full system scan with the full paid version and updated version of Norton anti-virus 2004! I was surprised that i had that many viruses when i had been running norton for 3 or 4 months running full system scans once a week and a quick scan once everyday. I later then uninstalled norton becuase my computer was going too slow and installed avast antivirus. The first scan that i ran with avast as soon as i installed it found another 24 viruses. That is a total of 129 viruses.
