NetNanny. It seems that online parents with better experience have voted NetNanny to be a trusted solution. With $39.99 annual subscription, it sounds like a good deal. It can be purchased online at www.netnanny.com.
I'm going to give it a try and will update here how it goes. If you have any experience, please drop a word. At any case, it's important to note that software protection is always just a part of the solution and cannot be the only step you take. Have a nice and safe summer!
