if you do a direct update it will install ALL items that come with avast. instead what you should do is download thenewest one (version 6) and then install it either over top of version 5 or the better way is to use the awsclear tool to remove version 5 reboot then do a custom install of 6 which the update feature does not allow you to do. i always do a fresh install anytime a major release version comes out of avast
