"Windows" maintenance and protection

It must say something that 8 of the top 25 downloaded applications exist solely to help protect or repair Windows from applications that take advantage of the many security and design flaws. It's a little sad that so much energy is spent maintaining something that was supposed to make our lives easier. At least for now, Apply computers are safe from the spyware, adware, and viruses that require us Windows users to reformat our drives or just buy new computers so frequently. Hmmmm....there's plenty more speculation that can be done along these lines. Anyways, check out the top 50 freeware and shareware apps on CNet's site. (I only counted through the top 25 b/c I'm lazy, feel free to append your count in the comments).
