What about spycop?

How do you rate it?

 

I like it a lot and have been using it for several years now.

It's not blazingly fast (especially if you're doing an "all files" scan as opposed to simply checking the ones created since the last scan) but it is exceedingly thorough.

Their tech support is first-rate, and if I'm not mistaken, their database for the total number of detectable keylogger programs is larger than any other.

The weak point is the "trial" program - I'd skip it entirely, as it isn't at all an accurate indicator of the programs' capabilities.

The license when you purchase is "lifetime" for both engine and defs, so even though (I guess you could say) expensive initially, it soon becomes very affordable (especially if it catches a keylogger on your machine). Pete
