Hi, best you wait for Dave, he has Avast free and can (hopefully) confirm it.
👍👍👍
I really can't speak from personal experience as I don't use ASB on any of my systems, since it can't be installed on all of them (no XP/Vista support), I haven't installed it on my win10 system.
Well I would say it is there (as an option) in the AvastUI Settings > General > Troubleshooting > Add/Modify Components as a selectable option (so would be there in a custom install). But as in the case of wittmann44 it doesn't appear to be doing the same as in other browsers.
My default browser is Chrome using Windows 10 and I have installed this extension on my Opera and Firefox secondary browsers.
e.g. as mentioned it isn't shown as an installed Add-on in ASB. The ASB may well have most of the functionality of the AOS add-on built in, but it doesn't show s an installed Add-on in ASB. Nor does it have AOS embedded in the search results.
