Avast! Internet Security keeps randomly disconnecting (Big Red X)?

[gtash0010]

Keep randomly getting the Bix Red X.  Click it on. Box Pops up to allow Avasti! to reconnect.

What is going on? It is happening about every 5 minutes of so.

How do I fix it?

The Box mentions if I OK Avasti Virus specifically to make changes to my computer
The Box Says:

Click yes, restores green check mark; however red sporadically comes back especially when opening gmail et.c

Help!?
