I removed XoftSpy last week, as I just don't trust it any more. If you read some of the threads on the Wilders Security Forums, it has a pretty poor reputation. I have played with several anti-spyware apps over the last couple of weeks, including CounterSpy, SpywareSweeper, AVG Anti-Spyware, and Cyberhawk, and found that all of them that offer 'real time' protection have some level of detrimental effect on performance, AVGAS being the least resource heavy. I have now decided to strip back to basics, and have Kaspersky Internet Security, Spyware Blaster and Windows Defender running, with Ad Aware, SuperAntiApyware and Spybot installed, but only for on-demand scanning, which I will do on a weekly rotational basis.
