"Also, of highest importance, DON'T USE OUTLOOK OR INTERNET EXPLORER." I get a little tired of this. It's a sort of "sky is falling" thing. In all the tiem I have been using them (since they came out) not me or any of my clients has ever had a attack come through those two programs. Why? BECAUSE WE PAY ATTENTION. Currently IE and Explorer ship locked down pretty tight... unless yous pecifically say "Yes" to a dialog box asking you to install something - they are extremely secure. This isn't complex, and there is nothing about them that is any more vulnerable than Mozilla, Opera or anyhting else. The simple reality is that if you run attachemnts you don't know he origin of, or if you don;t use anti-virus, if you aren't running a firewall then you will be vulnerable. The real cause thing "most responsible virus problems" is user ignorance and apathy. Switchign away from IE and then assumign you are "safe" isn't going to help.
