Being snoozed with inability to recover until entire system reboot/restart.

[CK1]

Hi, here is the info required from the read first list:

Step 1: Operating system and version info.

O/S Version:  Win 11 Pro v25H2 (OS Build 26200.8246)

Step 2: App name and version info.

App Name:  Kaspersky Internet Security
App Version:  21.3.10.391 (m)

Step 3:  Description of issue.

Kaspersky in the system tray keeps disappearing and trying to open the app does nothing until the entire system is rebooted/restarted.

Windows security page states "Kaspersky Internet Security is snoozed."

Event viewer states "Updated Kaspersky Internet Security status successfully to SECURITY_PRODUCT_STATE_SNOOZED." from source SecurityCentre twice in a row with the same timestamps followed by "Offline downlevel migration succeeded." from source Security-SPP approx 15 and again 16 minutes later.

The only information I've found in regard to this issue states its likely caused by Microsoft windows update and to just reinstall the app, I've done that, as a clean install with the removal tool twice now and the issue persists, restarting windows frequently is not really a solution to the problem.

Any ideas where to start? 

Postscriptum:  I should also say having exactly the same issue on a windows 11 laptop, only difference is that its win 11 home on the laptop, this situation is incredibly frustrating.

1. Any ideas where to start? 

Hello @CK1, 

Welcome back!

1.  Kaspersky Internet Security (KIS) -> is Kaspersky's *old* software - they've been replaced by Kaspersky Standard - Kaspersky is offering a *free* upgrade, Kaspersky Standard can be downloaded from:  https://www.kaspersky.com/downloads#update-product & please READ:  Kaspersky: Basic, Standard, Plus, Premium - info & FAQ
2.  It's (your) choice whether OR not to install / update a new version over the top OR do a clean install, IF doing a clean install - save LICENSE information only, after installing the new software - run a Database update followed by a shutdown - using SHUTDOWN, not Restart & physical-power-on of the computer -> login, *sign-into* the Kaspersky Standard app, so it *synchronises* with (your) MyKaspersky account - subscription/License -> monitor for the original issue? 

Please share the outcome with the Community, when it's available?

Thank you🙏

Can you tell me which thing I'm supposed to download, all of them I've tried are trial only.  I still have 160+ days on my active subscription and don't intend to start a new one until I know the issue is resolved.

Thank you for the assistance, I've gone ahead with the in place overwrite on the desktop system and it seems to have gone smoothly, usually the error occurred anywhere for 1 to 8 hours after initial login so I'll monitor the situation for today/tomorrow and post back one way or the other, it seems to have picked up my previous settings of exclusions and my login including my remaining subscription period without me having to enter my details.  Presuming it works out I'll go ahead with updating the other devices/laptop, desktop, phone etc still on the old application.

Just wanted to post back that this resolved the issue I originally ran into, thanks again for the assistance, I did unfortunately run into other issues after the switch which I asked about in a separate thread here (https://forum.kaspersky.com/topic/full-scan-quick-scan-stays-at-1-fixed-58770/) but these have also been solved by a new update.
