I sit here now with a fresh computer. While it may seem like a pleasant experience, it is not my preference. This is because my old computer was totally infected. If I knew then what I know now I would have learned how to remove Security Tool, the Trojan virus. This is what took over my computer. I did not realize that the  problems I was having were related to a virus. My computer was slow. I thought it was just overdo for me to run the clean manager. I think I was really hooked into this when I had a computer scan come up. It was bogus. I clicked it and ended up downloading Security Tool. Do not let this happen to you.
