If you shut it off and then restart your computer, and press F8 while it is starting up, you will (if your computer is anything like mine) go into Safe Mode. You can then go into either Settings, then into Control Panel. You will see System on the menu and click on System Restore, which should be a tab on the top of the box. From System Restore, you will see a calendar and you click on a date from say, a week ago, before the trouble started, and your computer will go back to how it was on that date. If you have picked up a virus, which this sounds like, it will take the computer back to a date before you got the virus and your computer should be fine. If this doesn't work, you can always call someone, a tech guy, and they can come out and fix it. This sounds fairly simple, Gary, and shouldn't cost a lot. Good luck.
