I heard about Spyware Blaster last night and was told that it was better than Spybot. So...I deleted Spybot and downloaded Spyware Blaster. Now that I've installed Spyware Blaster I checked all the boxes to protect my computer but am wondering about what may already be on my computer? I'm used to scanning for problems with Spybot and am not sure how this works. "Protecting" to me does not necessarily imply "cleaning up." It seems to me that I should scan for problems, clean things up THEN protect. Am I missing something?
