Blockster for Windows

This parental-control application is intended to block P2P programs from downloading without authorization, but its claims are unsubstantiated. Blockster is supposed to prompt users for their passwords when P2P file downloading is attempted. The program requires you to first register the trial by divulging your name and e-mail address. Though it tells of a separate database for downloading and installing, we never received notification of where to go or how to use it. Even so, we attempted to test the program using the built-in tester. Given that we weren't asked for the password we created at installation, Blockster told us to uninstall and go through the motions of installation again. Unfortunately, we ran into the same situation and, as a result, we were able to open and download P2P files without a hitch. Since this freeware doesn't seem to install all of its components properly, we certainly can't recommend it.
