I installed Avast internet security and banking site on Safe zone browser does not open. And when I closed banking site then, browser does not respond anymore and I have to close it by manager.

Perform a repair of avast.
If that doesn’t solve it perform a clean installation of avast.

I made repair, but stay the same. I can not perform clean install, because I have promotional license and was time limityed install.
