There is no need to direct you to any 3rd party offering or anything outside the OS. Nothing has to be added to Windows 8. One of the, really, cool things about it is, that excellent security is, already, embedded in it & ON, by default. Do not add or install such A-Vs, A-Ms or firewalls & you will no longer have any conflicts w/ Windows Updates.
All you need do to resolve this is completely remove Avast.
