I've been suspecting lately that my kids are looking at some "illegal" sites online. I installed a NetNanny-type blocker on the computer, but I think they may be finding loopholes. Some friends recommended this parental control keylogger to me, they said it is very useful. Though I'd like to install a keylogger to see what's going on, I don’t want to pay much money on purchasing monitoring software. Please, I will appreciate it if you can think of any free keylogger.
