hi, yesterday i installed avast! and after that opera couldnt load any page. i try to stop web protection and so on and it once go and once not. so i thought that i dont know how to treat with it so i uninstall avast but internet in opera still doesnt work. in firefox,chrome, IE works but in opera dont.I try to reinstal opera but still not, i try to uninstall, clear with ccleaner, delete opera profile than install again but the same. can you explain me whats wrong, if avast somehow block default browser or what if any other work and also all internet app work too.
