Church, you have a virus I am almost sure. Don't get charged more than $40 to get it fixed. The easiest thing to do, is get the disk out, put it into another machine that works, so you have 2 disks, clear the virus, copy the files and it's all done.
Let us know how much you are charged, I have heard of many people charging $100's, it's probably why I don't make money, I am too cheap, but it's easy!!!
