It is gray in Website where data collection is allowed.

Quick update... Icon does seem to be green on many web sites... but not here on this forum.. May be it "off" for this site as it is Kaspersky's and so is trusted... I dont know.. but it seems to be all good.

If you see the 2nd capture, it both modules says: Data collection on this website is allowed...

Thanks all... I can confirm the update to 21.24.8.522 was done manually, over the top of my previous install So I did as @newbie1 suggested and did a complete uninstall of the whole app and reinstalled. The extension then behaved differently to before... When it was not working, when I clicked on it in the list of extensions, it opened a box with a grey shield on the left, and an arrow pointing to (what I now assume to be) a settings screen.. clicking in that box did nothing. After the fresh install, clicking on it in the list of extensions did open a settings screen (as shown in @harlan4096 screen shot above). And once enabled things, the icon turned green as shown in attached screen shot. So I thought I was done and all good. But I rebooted, and now the icon is back to grey, but the settings do open, and seem to be selected, so I assume it is actually working (see second screen shot) Anyway - thanks for everyones help.

Сказал) Не забудь оценить качество помощи) А вот это интересно, если ты сам не менял... То кто или что поменяло....?

Мог бы тогда мне об этом сказать 🙂

Ну так продукт считает это не безопасным...

Да. Кто бы мог подумать что права на cmd.exe (причем расширенные, а не ограниченные) могут влиять на работу расширения. И возникает вопрос чего ради они изменились и в какой момент, если раньше все работало.
