I am running Kaspersky Total Security v 21.3.10.391 on windows 10 (x64 build 19045) and windows 7, and the browser extension on both computers slowing down and sometimes making un-responsive each and everyone of my browsers, Edge, Chrome, FF, all browsers are at the latest as of 2023-05-12.
On my Asus TUF windows 10, I can hear all the fans kick in when the browser starts hanging, I have verified that it is browser extension since disabling or removing the KS extension, will solve the problem, I have also on windows 10, completely uninstalled Kaspersky (VS and Extension) and reinstalled it and still have the same issue, I am not sure if this has to do with a KS update (exe or virus database) or some sort of windows update!!
Please advise.
