Avast 4.6 home Connection problems

Hi
I have been using Avast 4.6 pro, a computer problem required me to re-load XP. loosing all my license key info., all was saved in an e-mail file. I downloaded 4.6 Home to get me started. Because of an on-going problem Microsoft suggested I parallel load XP.
Everything was working fine until a few upgrades to Avast home were received and my system rebooted. Now I can not receive photos on MSN CBS or Yahoo News page. Also eBay is slow loading but without any photos. Unable to find the problem I rebooted to my parallel XP, all worked lighting fast as it should with 100m DSL Not having any protection I loaded Zone Alarm and Avast Pro taking the time to search and find the license information in my lost e-mail file. All worked
well! However going back to my other XP SP2 I have the same very slooooow connection and NO photos! I tried exempting the URL no good, I tried pausing Net Shield, No luck Paused all and again nothing but if I turn off on access scanner basically shutting down Avast Home all works great, super speed and photos! But No Protection! What can I do or what kind of setting must I make so that I can access e-Bay and the various news programs like MSN CBS and Yahoo ? I’m using IE Firefox seem most effected yet in my parallel XP both IE and FF work great!

Why do you say that with Home version you’re not protected?
Did you disable Net Shield or Web Shield?
