I repair PC's and Laptops for a living and the worst I've seen to date is a customers PC ( He had Limewire, which is just plain EVIL) with 43,000+ infected files as seen by AVG.
In the future , I'll take a screen shot if I can of massively infected PC's I get in my shop for ya.
Here's a pic of a PC that came in and the customer complained the fans were loud, oh and it was also infected with 23 virus's and he had NO anti-virus program
