Hello @DigitFish, Welcome! Please share the *full* Win11 25H2 *version & build* information, in Windows *Search* type WINVER, open the WINVER app, post back the information shown in the WINVER popup please? In the troubleshooting & problem determination/steps to resolve - has the computer ever been SHUTDOWN - using the *Shutdown* option - not Restart, a time delay of at least five minutes - then the computer restarted by pressing the power button ON & logging in? For *our* clarity, when (you) say: "Actually when I use Kaspersky Internet Security, sometimes this problem appeared. " - does that mean the red-icon issue pre-existed the install of Kaspersky Standard? Has Kaspersky Standard been fully *uninstalled* using Windows - Add & remove programs, the computer shutdown, using SHUTDOWN - not Restart, powered ON by pressed the power button, logged into & a *new* Kaspersky Standard downloaded & installed from (your) MyKaspersky account? IF 'no', please do this procedure, after installing the *new* Kaspersky Standard, make sure: The Kaspersky Standard is signed into so it synchronises with (your) MyKaspersky account. A Full scan is run. Run a manual Database update -> -> when these steps are complete - shutdown the computer *again*, using SHUTDOWN - not Restart, then power ON by pressed the power button, login, recheck the red-icon? IF the red-icon persists OR returns within the next 48hours & is not related to an app or module-update, log a support request, on the Kaspersky Customer Service page: https://support.kaspersky.com/b2c/global#contacts, select Email & fill in the template as shown; provide a *detailed-history* *Note: do not select the AI-bot to log the case* Please share the outcome with the Community, when it's available? Thank you🙏 Flood🐳+🐋

Галочку на первом скриншоте "Всегда доверять этому сертификату в последующих сессиях" ставить не пробовали?

Добрый день. Обратитесь в техподдержку. Нужны отчеты о системе, чтобы понять в чем проблема. На форуме мы не можем их запрашивать.

System Info Win11 25H2 Kaspersky Standard 21.23.6.614(a) Problem After restart my PC, the icon stays RED and never change to green. Have checked Kaspersky status --> everything OK and the GUI shows green when taskbar icon is red. (Weried) Press Win+Shift, icon turns GREEN. Or pause and resume computer protection, then restart again, icon shows green. Relative Problem https://forum.kaspersky.com/topic/kaspersky-protection-always-disabled-on-start-up-35843/ https://forum.kaspersky.com/topic/kaspersky-icon-appears-red-but-no-problems-detected-46656/ https://forum.kaspersky.com/topic/kaspersky-icon-29584/ Above relative links all indicate a restart could solve the problem. Actually when I use Kaspersky Internet Security, sometimes this problem appeared. However in my case, the only solution is what I write in <Problem> section.

Hello， 你这个网站跟 支付宝 没有啥关系…… 检测没有问题。

Hello， 我想问下，你 通知 设置里面对于 入侵防御 的通知设置是否是默认的？

Windows 11 home to the last november update, and Kaspersky Internet Security and Kaspersky VPN Secure Connection,

I don’t have the router VPN option either. However, a router that was already configured before the change is still working for me, although there are noticeable performance and stability issues
