Any bug or problem with the version of ??? System impact?
None, one of the best in performance. (That is not the last version of the application, the last one is 21.3...)


I have KIS at home and performing well.

In the office I have Kaspersky Endpoint and you can see, no impact in the system.

do you know why Kaspersky Cloud Free has a firewall enabled?

When going to the Windows 10 security dashboard and then through firewall protection > firewall notification settings > managed providers

It claims Kaspersky is off while Windows Firewall is on. Which seems fine.
However when clicking on the “open app” setting for Kaspersky there it allows me to go directly to Kaspersky’s own firewall settings.

I see that the firewall is enabled and when I disable it I got a warning from Kaspersky saying that “KSC cannot provide complete protection”

But does Kaspersky Cloud Free even need to have that setting enabled?
