I have read great reviews about this product and have long wanted to try it out. So last night I donwloaded the trial version. I know that many people have complained about false positives. I didn't get any, but my machine is fairly clean. Here are my initial impressions: 1. I like the GUI (interface). It is clean and easy to use. 2. I like the scan speed. It was significantly faster than Spy Spweper. 3. I like the thoroughness of the scan. It founded remnants of a Keystroke Logger that I had installed on my machine a couple of months ago that Spysweeper does not detect. 4. I like all the areas that it protects. Very similar to Spysweeper. 5. I like the fact that it scans Instant Messages. Even though I do not use IM presently, one day I might. 6. It doesn't appear to slow down my machine. All in all, I would have to say that after one day of use, I like it as much if not a little better than Spysweeper. HOWEVER, there were a few things that I did not like that might prevent me from buying it. 1. On installation, I told it NOT to install google toolbar. It did not install it, but did put google files on my machine. Why? I don't like google. They are the company that creates profiles on their users then uses those profiles to sell targeted adds. Not good for a secuirty company to be mixed up with google in my opinion. 2. The installation also tried to install a BHO. Isn't that why we want antispyware software, to prevent BHO's from being installed? Poor choice to have security software install a BHO in my opinion. 3. The trial product only scans but does nto remove spyware. I know that Spyware Doctor doesn't claim that the trial product will remove spyware. So they haven't technically done anything wrong. But it just left me with a bad taste in my mouth. As if they are saying: "if you don't buy our product, we don't care about you". After the scan, Spyware doctor told me that I had 46 registry entries remaining from an installation of PC Tattletale (a keystroke logger). But it wouldn't remove them unless I bought the product. That makes me feel like Spyware Doctor doesn't care about PC Security, and only cares abot making money. So while I truly believe that Spyware doctor is superior to most non HIPS antispyware products on the market, I'm not sure I'd buy it. There seems to be a certain "sleeze factor" that I am not comfortable with. If they would: 1. Ditch the association with Google 2. Remove the BHO from the install process and 3. Make the trial product fully functional I'd buy it in a heartbeat. I might even be able to look past the association with google. But not the others.
