Spybot , AdAware, and PestPatrol can spot, and remove, many but not all of them. In effect, loggers are Trojans, and are insidious. They do have a big following among divorce-oriented folks, though.
If you have a webcam, control of it can be hijacked if your security is weak. If you don't have the hardware, you've got no problem. If you do have a webcam and are paranoid, keep its lenscover closed when you're not actually using it, and plug in your microphone only when needed. Even paranoids can have real enemies.
lol!
Very funny.
Too bad about those divorced people. They should get over it and get on with living. Life's too short.
