I am also having an issue with slow browsing or pages not working correctly. When using Chrome the message "waiting for gc.kis.v2.scr.kaspersky-labs.com" is displayed in the lower left of the screen. If I'm using Firefox or Edge no message is displayed but the results are the same. I have safe browsing turned on.
I have disabled the check box under network settings but it is still occurring.
I am using Windows 10 version 22H2
Kaspersky Standard 21.14.5.462
I have been having this problem for around two weeks.
I have issues with google search, gmail, youtube, google maps being slow or not loading which may or not be related. I give some examples below:
Google search will not function with Firefox at all but Duck Duck Go works fine. Using Edge I am able to search using Bing and Google search functions with Chrome though both can be slow at times. I do not like using either Edge or Chrome.
Gmail will only function when using Chrome and then sending emails does not always work and I am unable to attach files.
Youtube functions under Firefox but the search function does not work and navigation is limited. Youtube operation when using Chrome is slow.
Online gaming and streaming does not appear to effected. It just seems to be anything involving google products.
