Kaspersky 26.0.0.150c.d breaks or uninstalls Kaspersky Protection Extension for Safari

[Tantalus]

Hi,

When .d update for Kaspersky 26.0.0.150 is installed Kaspersky Protection Extension for Safari and its icon automatically disappear. Kaspersky app tells you Safari Extension is activated, but it really no longer appears as an extension installed in the Safari app.  This only happens when D version is installed. No trouble with 26.0.0150.c.  The problem is than installation of the newer version is mandatory, and not an option.  Please check this issue.  Uninstalling and reinstalling Kaspersky doesn't solve the problem.  I've checked a couple of times on Macbook M1 Pro and latest MacOS software versions installed:    Tahoe 26.3.1 and Safari 26.3.1.

Hello.

The problem occurs because the Kaspersky Protection Extension for Safari is now unsigned. By default, Safari will not use unsigned extensions.

To use the extension, you need to go into Safari's settings -> Advanced -> Check (click) the "Show features for Web developers".

Then go into the "Developer" tab and check (click) the "Allow unsigned extensions".

The extension should then become enabled and appear in the usual place. 

This issue can ONLY be resolved by Kaspersky getting THEIR extension signed.

Hello.

I have been advised by support that this issue has now been fixed.

I did a clean install of Kaspersky Premium on my Mac Studio and the extension now appears as expected.
