The program is produced by PC Tools in Australia, I believe. I don't know
if it's a an offshoot of the old PC Tools of MS-DOS days. I purchased the
program on the basis of the PC Tools name (rather irrational, huh?). They
have several programs along this line, and Spyware Doctor seemed to do a
very good job... BUT, I have 2 programs which are more important to me than
Spyware Doctor, which that program affects; so I had to uninstall Spyware
Doctor. Those 2 programs are Photodex's CompuPic and Inbit's FullShot.
CompuPic would not respond to some hotkey commands and did a couple of other
strange antics. FullShot (a great capture utility) would not execute on the
Internet where I use it most.
PC Tools readily offered a trade for one of their other products; I declined
simply because I had similar products which I preferred. You might take a
look at their website. I don't have the URL handy but Google will turn it
up. Somewhere I read some reviews on this program, maybe ZDNet or CNET, and
user's reviews were quite mixed.
