I mean is there any protection which prevents browser from execution of virus code(which is received from internet page as the result of use of browser engine bug)?
Such feature present in Kaspersky Antivirus. I want to know whether it present in Avast products?
avast has the webshield and AOS.
And in Avast! paid products you have a Sandbox, so you can isolate your browser from the rest of your system.

Thank for answers. I must admit that marketing of Avast product is bad. There are no information about this technologies on the company site(at least Russian one).
Can you elaborate on this ?
Obviously I don’t speak Russian. But if there is something wrong, you maybe can help me to put this forward, so it can be improved

There is a lot of information on the Russian website about it.
