Call Microsoft toll-free number 1-866-727-2338.
I kept hitting redial until I got through. Then they gave me a case number (write it down) and transfered me. I was then on hold for 2 1/2 hrs! I had put the phone on speaker, cooked dinner, ate dinner, made some cell phone calls, read mags, etc. When they finally answered they fixed it right up.
He said they had 9000 calls already and over 200 on hold. Yikes.
Running out to buy a Virus Scan now.
Good luck.
