Avast! 4/Java problem?

I did away with Nortons and downloaded the Avast!4 Home Edition, but there seems to be a compatibility issue with Java or Adobe Flashplayer. Cbssportsline.com utilizes a live scoring system for its fantasy sports using Java and Flashplayer to automatically update scores and stats. This feature stopped working after installing Avast, and when I uninstalled Avast it started working again. I am happy with Avast otherwise and would like to keep it. Are there changes I can make to the settings of either Avast or Java/Flashplayer to correct this problem? I am operating an Acer notebook with Windows XP and the Windows firewall. I encountered no other issues while Avast was still installed.

Not that this will be much help, but I also play CBS.Sportsline.com fantasy baseball, and have never experienced the problem that you reference. You may want to be sure it is the Avast and not something else. I have Windows XP and Windows Firewall, so maybe there is something with the Acer versus my Thinkpad.
