Spyware Doctor

I just want here to confirm what Justin said in his message below. I've also used Spyware Doctor, more than a year ago. Just before that, I was using several anti-spyware programs at the same time,until I realised that Spyware Doctor could replace them all, and even do a better job. Unfortunately, the program became very resource demanding, and occasionally conflicted severely with other applications on my system. That was the end of my relationship with Spyware Doctor. Despite an obvious change of behavior in a windows environment, Spyware Doctor remains in most reviews one of the 2 best anti-spyware, together with SpySweeper, that I never tested. I promise that I will, and report my experience in this blog.
One thing though, don't be abused by the button "START SPYWARE SCAN NOW", it does not mean that you will get an online scan of your drives; in PC Tools language, it's the download button for Spyware Doctor. I do not not appreciate such marketing methods.
