You should contact to Kaspersky Support, because for K. that certificate application is Untrusted, that's why it is moved to Untrusted group. Anyway, You may try to disable in Application Control / Intrusion Prevention:

 

 

And check if still even moving to Trusted manually, again it is moved to Untrusted.

 

In fact, I have that always disabled, but my config try to emulate a Default Deny / LockDown:

Hello, @rufford155

Please select it and press Details button and then check whether the Digital Signatures provider is its self or not or take a screenshot on it, let's know the situation.

Don't see why KIS doesn't like it - but see my next post.

[rufford155]

Here's the latest problem - yet another store app that KIS objects to !

Someone please convince me that this is not KIS against the USA !

Certificate problem yet again !   Supposedly.

Hello,

I have checked this installation file about its digital signature.

Do you uncheck the KL application control settings : trusted digitally signed application? By default, I can not encounter this issue.

It is not a self-signed digital verification. I change my previous idea. This file is signed by Sectigo.

As for why Kaspersky does not trust the sectigo certificate authority, this reason requires Kaspersky to confirm the reason.

Regards.

Wesley,  I have unchecked that but it made no difference.

It seems that every new app, program, even updated ones, is put into restricted by default.

When I click Allow and Remember on these popups, KIS forgets.

It's becoming very difficult to get anything done with KIS in the background.

I am on the verge of scrapping it and wasting half a year's subscription.

Is KSN working in Your KIS?

[rufford155]

Yes it is.

But I've noticed it does not report Trusted - only Unknown - for the Minitool installer.

It's odd 'cos I have definitely installed that program in the past (on a different laptop).

[rufford155]

I have just looked at the Kaspersky web page How to change Application Control settings.

I never realised before how much KIS was able to interfere with my system.

The number of settings are far too complex and confusing for an ordinary consumer.

I am turning off Application Control completely.

[rufford155]

Still got warnings from KIS even after turning off Application Control.

It won't give up !!!

[rufford155]

I have 2 new ones it's objecting to now !!!!!

See my new post.

Hello @rufford155, 

Welcome back!

Why open a new topic for the same issue? ?

Have you reached out to Support yet? 

Thank you?

Flood?+?
