If you don't do these steps and have a G-Mail account, will your G-Mail still be scanned by Avast? I always see Avast scanning G-Mail when my computer client uses her G-Mail account on this computer.
That tutorial showed a lot to do, that still might confuse some people. I don't understand as G-Mail is not ISP dependent, but off of Google's servers, why would you have to do this configuration for G-Mail?
Shouldn't Avast be able to scan your Outlook Mail once the ISP settings have been set up and the incoming/outgoing settings are correct?

I think this answers my question: (Taken from Avast FAQ)
How does avast! 5.x secure web based e-mail services such as Yahoo, Gmail, etc.? Web based e-mail services such as Yahoo, Gmail etc. usually have their own security options, because e-mails are received and stored on the remote Mail Server and users access their e-mail accounts remotely via their web browser. In other words, web based e-mail services are like any other website, and if you try to save, download or run a suspicious file from a web based e-mail account, it will be detected by the web shield built into avast! 5.x.
As a result you should not expect to see any scan history in the Mail Shield screen if using a web-based email services. If you have any doubts about the security of your web based e-mail service provider, you can alternatively launch your web browser within the avast! Sandbox and then access your web based e-mail account within this secure virtualized environment.

PS. Although the above is for Avast 5 in the Help files, I assume that Avast 6, follows the same procedure.
