You know, the more I live without a backup, the less need I see for it. I haven't had too many issues. So it may take a little time to rebuild. Chances are a fresh start would do you good anyway. Or so I would like to think.
Anyway, I can understand everyone working to get things in place for when a virus does hit. They're just trying to make sure they are the first AV you see when the need happens to show it's face. It's my guess that we've still got some time before this is of any real concern. But that's just my thoughts. I could be wrong.
