myself a few months ago when I switched to avast. This link below is from the avast support, It has screenshots and directions for the settings in both the avast program and most e-mail clients. I have OE and Windows Live should be the same, It is easier than it looks.
Dell Intel Core 2 Duo Processor E7500 Computer
Inspirion 545s 00
Windows 7 Home Premium 64-bit
750GB Hard Drive
Wireless N Networking
I just downloaded Avast and got a popup box saying the following:
"avast! has detected a secure connection from your mail program (process wlmail.exe) to the POP server 126.96.36.199 (gmail.com).
This type of connection cannot be checked for viruses. Please disable SSL/TLS in your mail client so that the Mail Scanner can scan your mail. The Mail Scanner will provide the SSL/TLS security itself."
How do I disable the SSL/TLS in my Windows Live email program?
