Download the BHODemon software and it will most likely cure your problems.
If you have a more insidious problem, follow ALL of Dan's steps and you'll get clear of it. After you get through, leave the BHODemon active and it will catch anything that tries to latch onto'ya !!
Good Luck, and Take Care.
