LL,
In order for me to help you, I need some information:
What OS are you using?
When you said you were updating, what were you updating....Program or Database?
Were you updating manually or automatically?
What exactly was the message you received?
Did you run the Detect and Repair routine? If so, what result did you obtain?
At this point, I cannot say for sure what transpired, but I would suspect a file corruption occurred.
You mentioned that you were going to try a download.
Make sure that you completly uninstall the version of Avast that you have on the computer before trying to install a new copy.
Let me know if you make progress.
