Hello Mr. McLean,
If you're still monitoring this thread I have some questions re SS version 2.0 which I think is the latest version. I downloaded the trial and was quite happy with it, especially the easy to use interface which to me is worth paying for compared with much less intuitive interface of Spy Bot. But I saw a review (I think in PC World?) which said that SS caused great instability in Win XP when run with Norton AV such that a reformat of the HD was necessary!!! I've also read posts saying it has serious incompatibilites with Windows Media Player WMA files and Windows Update and perhaps other programs as well. I have a lot of programs running in the background including Diskeeper, Quicken, Drive Image,etc and am very worried about potential incompatibilities with Spy Sweeper. For these reasons I untinstalled the trial version.
It also seems to use a lot of memory when running in the background (around 18 megs on my system).
If you can provide good evidence that it is stable and safe to run with the above programs (and games

) I will purchase the program.
Thanks for any help,
Carl
