Also what version IE
I guess there is still no real time fix for the automatic popping out of the avast internet security. I will just keep closing the tab until there is a solution to it or try the suggestion of cod head. 
Was having the same problem when opening Firefox.
To fix try this:
Click on Firefox drop-down tab. Then go to Help, which opens a menu > Open “Troubleshooting Information” and look for the “Reset Firefox” button on top right side.
Click on “Reset Firefox” and let it do its thing.
You should be good to go after that!
That will work, as Firefox will start saving all cookies again. Also, resetting Firefox will remove almost all of the customization anyone has done in Firefox.
Tnx for the reply guys, .
