I have no browsing problems at all with this version. I think people who do have problems, have got remnants of other AV programs that they have removed, but not cleanly. This has happened to me in the past. Download AV program cleaners from the company that you had installed before, and maybe re-install Avast again.
Hope this helps, it seems impossible that Avast is giving the problem when so many people are not seeing the same problem as you.
