Welcome back. I was wondering where you had gotten off to. Glad it was no more than a computer virus and you weren't sick yourself. Computer viruses can all be taken care of eventually, even if, like you said, you have to format the drives and start from scratch.
You might try AVG virus protection. They have a free product that I've been using for the past couple of years. Cyndy turned me on to it. It's wonderful. I've not had a single virus since I started with it. The web site is www.AVG.com
Lots of love and healing hugs,
Dan
