You didn't say, but you should uninstall McAfee. It is one of the main
troublemakers. After you have uninstalled, get the rest out using the tool
here: http://tinyurl.com/yohh76

You will find that the free AVG or AVAST anti-virus programs are more
compatible with Windows...

Go to Tools, Accounts, select that mail account, Properties, Servers.
Uncheck the box for "Log on using Secure Password Authentication."
If that was already unchecked, which antivirus are you running?
