I guess I need to know how to check which plugins are installed.
We Installed the SEP Software on the Server, exported the client install packages to a shared folder, and then Downloaded the Client Install packages and ran them on each client.
I don't remember there being any options as to which E-mail Plugins to install?
For the Windows 7 box, this was the Only Anti-Virus, there wasn't any previous product.
For the Windows XP boxes, it was Symantec Coporate Edition for Small Business V 7.6
This was First Uninstalled using CleanWipe_11.0.5002.333
The Windows 7 box is the one Most affected. With Auto Protect turned on, It easily takes 2 to 10 minutes to open an E-mail that has images as attachemts.
Our Internet connection is a T1 at 1.54mips
I did monitor what is going on with Systeminternal Process monitor.
It looks like the Attachments are being routed out to an IP address while all this waiting is taking place.
