Welcome to Kaspersky Community. Hum it should detect the new Subscription and start using it...

The 3 files are not detected now.

Birkaç gün önce destekten yenileme yerine bana yeni bir indirimli abonelik linki gönderdiler. Aboneliğimi iptal edip indirimli olan tercih ettim, Desteğin için teşekkür ederim.

Welcome to Kaspersky Community. KFree has been stopped (You can't find the installer anymore in official K. sites) in most of the western countries. Still the already installed KFree continues working so far, until when? I don't know...

更新卡巴斯基21.24.8.522后在火狐启用卡巴斯基插件会导致卡巴斯基自动退出后重新启动，而且在该过程中并没有程序崩溃的弹窗告警。在23版本的KIS中则一切正常。火狐版本为147.0.2 (64 位)。在浏览器里停用卡巴插件后KIS没有再自动退出重启。

Welcome to Kaspersky Community. I will try to report those 3 files, still, about your request: I would create a ticket in official Support K. Support, since They can escalate your request to upper developers.

@Dm111, попробуйте переустановить программу. По той информации, которую вы даете, больше ничего посоветовать нельзя.
