Kaspersky Security Cloud blocking Windows Update and other apps

[Chongoat]

Hello there!

I was hoping to find assistance, and find out if there is a setting I can change to fix my problem.

Since yesterday, I started noticing some apps stopped working properly. Namely, the Epic Games Launcher, and Microsoft Start (the native feed to Windows 10).

After some experimentation, I realized normal functionality was restored after exiting KSC.

Today, I noticed the exact same pattern with Windows Update (KSC was blocking updates from being transferred).

I tried isolating the problem, switching off specific components of KSC but couldn’t find one that was causing this issue.

Anyone had this same problem recently? Running Windows 10 (21H2), btw.

Thanks.

Thank you for your reply.

I can confirm my KSC version is 21.3.10.391(g).

Looking at the KSC reports, I’m not seeing anything abnormal, apart from more than a few “Not Processed” events under the File Anti-Virus reports, but I have not idea if they represent a problem.

Regarding the Windows Event Log, I’ll admit not really knowing what I should be looking for… But there doesn’t seem to be anything anomalous, besides a number of warnings about the...COM Security Policy?

@ChongoatYou are welcome.

Can you please post a screenshot from the “Not Processed” events.

Well, reinstalling seems to have solved the issue.

KSC is now running and previously blocked applications appear to be working properly.

I should have thought of trying this sooner 😂

@Berny , I appreciate your help.
