I suggest that you read the info on the virus and apply the patches and update your virus/os patches etc...

If your lucky that is all you will have to do.

But you must follow the instructions exactly.

Then you should look at automaticly updating your virus software daily and automaticly updating your windows software.

I know it is not very proactive. But at least you will be doing something.

Rebuild is a Last resort.

I am recommending you to follow this approach. This is the current approach I use at work.
