ehh... too much but I recommend not go wrong way and get more info about prog (by some search engine and words "you prog namne spyware/help/problem") that you want to download b4 downloading.
This page have much descripton on bad "Anti-Anti"_progs "follow" them who have "good" reputation
That's a nice article you have there! But I think one more addition will help. Try Secretmaker from www.secretmarker.org. It is a great app... running in the background it helps with things like changes in searchpage/homepage addition/modification to the startup programs etc. It's also got a nice random password generator built in!
