Hey,
I don't know much more about Superantispyware, Spybot, Adaware, Spywareblaster because i have not use these anti-spyware yet, I do a big mistake when I used Adware Alert antispyware which I purchased from www.adwarealert.com, This is really very bad antispyware, that is rogue & not well working, its damage internal parts of my computer system..
Cheers
