Well, at least their advertising companies do. I don't normally go to that site, but starting with wanting to update the CPU history chart that I have downloaded from their site, I started to browse

As I use NoScript with Firefox I don't normally see any dodgy ads, but when I wanted tomshardware's 'page picker' combo box at the bottom of an article (I was reading about the Phenom II), I first temp-enabled tomshardware.com, no difference, then I thought 'screw it', instead of enabling one site at a time, I enabled the lot. Then I was constantly badgered by WinAntiVirus2009-like "YOU ARE INFECTED" type stuff.
