We use something called Spector. You can get it at Spectorsoft.com. It is a keystroke logger, that has "hot keys" to bring it up. It is password protected, so even if they can figure out the hot keys, they would have to know the password. It runs in stealth mode, doesn't show in the program log, or registry. So they cannot find it just surfing around. It records every keystroke, and takes screenshots every few seconds. I've found it an invaluable tool raising teenagers.
