MoreI think the paid version of spybot is worth it, they beat the price point of the competition and it works well, also I like the fact I can see what virus's it's searching for, and what it's doing at any given moment, where as Windows Defender treats it's user like a moron, and shows you nothing, and won't let you see "threat details" until after you remove the issue. Why? Well because Microsoft doesn't like software competition and labels many applications as a virus, like Nvidia for instance, basically they try and put the big scare into you and make you remove perfectly good software(or break it). This is called a "false positive". I would recommend Spybot to anyone.
