Patch C for Kaspersky Internet Security version 220.127.116.111 was released on June 3, 2021.
Confirmed at https://support.kaspersky.com/15595#18.104.22.1681c
Today is 10 June and I didn’t get it through KIS update!!! Update is working fine but there is no indication a new patch had been fetched from K-lab servers.
Did you get Patch (C)? Is it rolling slowly?
Thanks for sharing and responding.
