Is OK TO have SpywareBlaster and Spybot + AD-aware???

The only problem with multiple programs is when they both scan or run in the background at teh same time. With Vista, you already have Windows Defender (unless you turned it off yourself). SpywareBlaster isn't a program that runs, so much as a set of settings that stop malicious active x controls, so that won't matter. As long as niether Spybot nor Adaware are running at the same time as Windows Defender, you should be ok. I do fine with the Mozilla Firefox browser, one spyware program running in the background, and then another one for a periodical scan (in addition to antivirus). I don't think I'd use three antispyware aps, but there's certainly nothing wrong with it, again, as long as they don't run concurrently.
