Apart from SpywareBlaster I don't use anything else, although I have to admit I don't surf the net anything like I used to, so it is no great surprise for me that Ad-Aware never picks anything up "with the exception of the odd tracking cookie"

edit:
This new Anniversary Edition is certainly much faster than previous versions and also has a automatic update, even in the free version.
Although the pop-up add gets a bit annoying but I think I found a setting to turn of the notification in it's setting, but need to wait to see if it comes again.
