The new Security updates that came out today gave me a little problem.
I received the following error message: [Error number: 0x80072F76]
In order to fix this problem, I needed to disable the Proxy Server set up for the avast! Web Shield
Tools, Internet Options, Connections, LAN Settings, UN CHECK Use the Proxy Server (127.0.0.1 Port 1280)
Once that was done, I was able to access the Update Site.
Remember to re-enable the server if you intend to use Web Shield again after the update.
