computer crash

It really sucks the way companies put effort into sabotaging our computer systems, then want to charge us to buy products to remove there spy ware, trackers, worms, and all other types of foul computer diseases. That's the world that were living in and mostly we have to just go with the flow. The risk has always been there with computers. as a matter of fact the only time that I haven't been attacked through my computer is when I didn't have an internet connection. I am working with various freeware and shareware programs ,which may or may not add to the problem.meaning that I have paid for virus protection programs and still my computer got infected. that's one of the main reasons that I don't use Norton today.
