text: how can i block a certain website from my computer??? my adult kids have myspace accounts, i have one too.  the problem is that when anyone goes to myspace on my computer it bogs the computer waaaaaaay down...almost to the point of freezing up.  i've asked my kids not to go there anymore...but after checking the history, they still do...so is there anyway i can block myspace from being accessed from my computer???  thanks...
