You're on the avast Settings...
You must start the On-line protection window: LEFT click the 'a' blue icon.
Choose Internet Mail provider.
Click on Customize
Go to Advanced tab...
I was lost because I thought this option was in the Program Settings. Left clicking the A blue icon displayed the avast! On-Access Scanner dialog. Then I add to click the Details button to find the Internet Mail tab.
Thanks I was able to set the
Timeout for Internet communication to 600, I will try 0 later if the
Connection timeout dialog keeps popping up.
Just a suggestion but I think you should rename the Details button to Advanced (Settings).
Thanks.
