I just installed this program a few days ago....I had a 6 months free subscription with the PC Pro magazine......and i must say this prog is well imressive.
It has lot's of features:
Cookie Guard Start-up Guard Browser Guard Immunizer Keylogger Guard Network Guard Pop-Up Blocker Process Guard Scheduler Site Guard
This fab program has already rid me of a lot of spy's and also stopped a lot of them from installing....It does all this actively in the background and doesn't seem to have any effect on system performance whatsoever.
I shall certainly buy this when my free sub runs out.
