I have more than eight " Anti-Spyware " installed to my PC. They are " Spyware Doctor"," Spy Sweeper "," Ad-Aware SE Professional"," McAfee 2005 Anti-spyware "," Spybot Search & Destroy", " SpyCatcher from the GhostSurf 2005 Platinum Suite ", " Bazooka " and ' Spyware Begone ". Last week, one of the cnet.com modorator commented that ' Spyware Begone ' was a no no. I can say from experience that " Spyware Begone ' is doing a good job as lately my default web-site had been changed. I used all the " Anti-Spyware " to detect what was wrong of it. None of them could tell me that my web-site was being hijacked until this afternoon, I used " Spyware Begone " to run a scan. Immediately it detected I had seven spyware in my PC and deleted them afterwards. Now my default web-site is back. Thanks to MicroSmarts of the " Spyware Begone version 6.75 ". The worst " Anti-Spyware " I have are the McAfee 2005 " Anti-Spyware " as it keeps on bugging me there is an update but each time it was the same version as I installed it in October and they are very slow of sending you the rebate too. The Webroot " Spy Sweeeper " is useless and expensive. Though it has the " Alert " feature yet my default web-site was being hijacked and it did not alert me. So both McAfee and Webroot are junk. The Spybot Search & Destroy always comes up with the same " DOS exploits ", cannot complain as it is free. ' Ad-Aware SE Professional " by Lavasoft used to be the King of adware but it only catches big spy and failed to detect the small spies. So in a nutshell, go for " Spyware Begone version 6.75 " because it is the only " Anti-Spyware " to detect your web-site being hijacked in the very first place. a2 has lots of problems though it is free, I guess they want to push everyone to a2 personal. Lots of problems. If the softwareis free, chances are they are spyware themself. One time I downloaded the SpyBlaster and immediately I had 17 spies detected by Spyware Begone. Both SpyBlaster and SpyGuard I had downloaded a fortnight ago and I suspect they are spyware themselves. Last but not the least, forget McAfee and Webroot coz their software are lousy.
