The Internet Mail provider plays no part at all in viewing Hotmail via the IE Web browser, so those heuristics do not come into play.

However, I can also say that I have no problems with Hotmail Live accounts being viewed in either Firefox or IE7 (sorry I no longer use IE6) with WinXP SP2.

Perhaps you could try a little more “fine tuning” to see if the problem can be isolated rather than uninstalling avast.

The avast component that will be scanning the connection when accessing Hotmail via the Web is the WebShield. Does it make any difference to accessing your Hotmail if you turn off the Webshield?
