Query: Wish I hadn't bought it!

I bought the previous 2 versions of Spysweeper with no problems, but this thing is a headache. When it comes on suddenly (there is no warning), it completely drains the computer (and mine has a huge amount of memory), everything fades, and whatever you are doing gets locked up. It will not shut off, either, when "stop scan" is clicked. To do a full sweep it takes several hours, over 6 and still sweeping, and in the meantime the computer is locked up, and you can't do anything else. Either the computer crashes if other programs are open, or they sit there faded and locked up. The only way to stop it is to shut off the computer. I finally had to shut off the full sweep setting and just use the quick sweep which is an option.
