I have been using this to monitor my daughter's PCs for the last 5 months and I have been very pleased. It shows when they have used the computer, what software they are running and how long they spend on the internet as well as what sites they are visiting. It also tracks their msn conversations.
One feature that I especially like is that I can access the logs from any computer, so I can check what they have been doing without them knowing.
Other features include a virus checker and Time Controls, so you can limit who can go on the computer/use the internet and when. The cost includes a license so that it can be loaded on up to 3 pc's this was all for $40
I'm looking for a program to monitor my kid's internet activity. I've read about a monitoring program called Spector and it sounds pretty good. I would appreciate any opinions/recommendations on this subject.
