Cela fait plus de 10 ans ,si ma mémoire est bonne que j'utilise Kaspertsky sans jamais avoir de problème.

very good

This works for everything but YouTube. It is blocking *some*thing that keeps me from seeing my history, playlists, etc., and produces a YouTube 405 error.

Very good. Needs to sync with the frequent pop up that irritatingly insists that you sign up; there doesn't seem to be an acknowledgement that I am already signed up.
Please fix this irritating bug.
