Here is what I just posted athttp://www.mywebattack.com/a/about Avast:
Avast! is extreamly easy to use and setup. It catches viruses Norton leaves behind.
Avast also has one of the best and most active User Groups around. If you have a problem or a question, simply post your question and you’ll receive prompt useful help. I would never go back to NAV or any other Anti-virus program.
