Internet Connection timeout

[The Stroumpf]

Hello
 I got one more problem, and I hope then I will be all set...

I get every few minutes this error message from avast:
"Internet Connection timeout, should I continue waiting?"

what's that?

I have a flat-rate DSL connection and am usually online when the PC is on.

Why do you think it's an avast message? Isn't it a message from your mail client program?

No, it's in an avast window, it gives the name on top and it has the look of the avast windows. I am trying one setting that I found, right now (just booted up) lets see what that does:
In the control for the 5 different services, in Internet mail, I found a setting under 'Advanced' that says "Timeout for Internet communication". I set the value to 0. No idea what it does though.
