Firefox unable to display

As posted by Aron Davidson, Following the latest AVG update Firefox will not load.  I too am using XP. The egg timer starts showing that Firefox is trying to open but it stops before the the homepage loads, with no error message.

Coincidentally, I'm also now unable to download Flash Player.
