From Wikipedia:

"Windows 7 was released to manufacturing on July 22, 2009,with general retail availability set for October 22, 2009, less than three years after the release of its predecessor, Windows Vista."

Here's a quick rundown of the Windows Firewall settings required for AVG 8.5 to successfully install remotely.

I have provided these in Windows "GPO" format, as pushing the settings out through your domain's Group Policy is probably the easiest way to do this.

I recommend NOT installing the AVG firewall (if you have Internet Security) in a domain setting. Use the Windows Firewall, I think you'll be happier.
