Lately I have been having a lot of trouble with my computer.  Not only is it running really slow, but I’ve been getting these notifications that my computer is infected with a virus.  It seemed a little odd to me that every time I got a notification I was directed to a site that was selling an virus removal program.  This made me start doing some research.  I discovered that my system had be invaded by a program called security tool.  Next, I started trying to figure out how to remove security tool.  I found a very helpful site that explain what it was and how to delete it.
