I had this issue of Kaspersky plus not responding when I try to open the app, so I uninstalled and reinstalled the app. It fixed the issue for 4 days, then it reoccurred. The Kaspersky logo is on the icon tray when I restart my computer but when I left click it, nothing happens. The app briefly opens when I restart my computer but then it immediately stops responding before fully loading the UI
I got that too, think it’s a glitch with a recent update. Restarting the pc fixes it. Although it is a bit annoying having to restart the pc whenever it doesn’t respond, so I just launch it as soon as I turn on the pc.
I had to update my databases by using a VPN pointed to Canada to get mine to work.
