Does anyone know of a free, reliable computer filter that restricts access at certain times of the day? AFAIK, only K9 does, and that's what I'm using, but it causes terrible problems. Every once in once in a while, as soon as I connect to the internet, the BSOD comes up and the computer restarts, saying that the was some type of registry error with bckd.sys (which is K9). It's really annoying, and I'd really love to delete it, but I can't find anything else with time-based restrictions.
