Avast won't update.

Dell, Win7-64

I updated my Avast to the latest version (5.1.889) yesterday and now I can't update the latest definitions. When I try, it says "Last encountered error:Invalid file signature. Set up will terminate."

Current registration will expire on:2/6/11

I have never had any problems with Avast before. I have tried all the suggestions that I found searching the archives, but still not updating.

I have rebooted, but have not tried system restore.

TIA

Jean
