 Hi all.

The problem in macOS 13 itself (when upgrading from the previous version).

To solve the problem, among other things, you can do the following:

1) Open the main window of KIS\KSC\Kaspersky; you will see the red notification.

2) Click the "Allow full disk access". "Privacy & Security" tab of the System preferences will be opened.

3) Right-click on "Kaspersky System Extension" > Show in Finder.

4) Drag the extension from the Finder window to System preferences window. Full Disk Access will be given.

 

or use this guide:

https://forum.kaspersky.com/topic/antivirus-broke-after-the-upgrade-to-macos-13-ventura-28823/?do=findComment&comment=118049

 

or use this guide:

1) Uninstall the product

2) Restart macOS (very important step)

3) Try to install the product once again.

If there is still no possibility to give full disk access:

4) Open System Preferences > Security & Privacy > Privacy > Full Disk Access

5) Manually drag-n-drop system extension (navigate to Go > Go to folder and copy-paste the path below):

Kaspersky for Mac (new 2022 application):

/Applications/Kaspersky/Contents/MacOS/Kaspersky System Extension Daemon/Contents/Library/SystemExtensions/

KIS for Mac:

/Applications/Kaspersky Internet Security/Contents/MacOS/Kaspersky System Extension Daemon/Contents/Library/SystemExtensions/

KSC for Mac:

/Applications/Kaspersky Security Cloud/Contents/MacOS/Kaspersky System Extension Daemon/Contents/Library/SystemExtensions/

 6) Disable and enable application permissions once again

I tried all the steps above and none of them is solving the problem. There is one item I cannot remove by no means: Kaspersky System Extension. When I open it in Finder it takes me to: 

/Library/SystemExtensions/AE6335F5-83A4-43CF-8E68-4A1CA0F6EF32/com.kaspersky.kav.sysext.systemextension

That folder cannot be deleted. It remains even after uninstalling everything. I cannot remove it in Terminal neither.

Same exact issue. Moreover, after updating, all my internet connections went incredibly slow. After long trial and error, I fully solved by disabling the Kaspersky IDS content filter under "filters and proxies". No idea what exactly this is, but with this OFF internet got back to normal levels, while with that ON as it was by default any internet connection seems back to the 80's.

 

Exactly same problem ... but are these two important features? or is it okay to disable it? 

I uninstalled Kaspersky completely, but the "Kaspersky System Extension" item still appears in Full Disk Access. I've tried clicking the "minus" symbol to remove it, but it appears back after a few seconds.

If I right click and go to "Show in Finder"

It shows me this folder, and I cannot delete it:

BTW,  even after uninstalling I had to disable both Kaspersky Filters for my internet to stop slowing down. For those I was able to delete them by clicking the minus ("-"), but now I'm worried how can I reinstall the antivirus if I'm not sure all previous files / folders got deleted... hoping you can help me with that.

Also, by reinstalling and providing Full Disk Access, which I wasn't able to do before, would the slow internet issue stop?

Thanks!

I have followed these steps and still unable to install Kaspersky internet security. Screenshot attached of where I'm getting stuck at. 

Applications > System Preferences > Network > Advanced > Proxies and deselect any proxies that have been selected.

Disable your kaspersky there does the ticket. I deleted all kaspersky from the application part of my mac. I am so disappointed in apple for doing this. It was not just Kasper who was impacted by this. Malwarebytes was and while googling this I saw other antivirus companies with the same issue. I felt like I was on windows how slow my computer was going. To even read the thread in here I had to do it from my phone. 

Will Kaspersky notify us once we can fully use their software again? I cannot afford to have it on my computer until they fix it to work on the new updated macbok ios.

Fix this by REMOVING AV COMPONENTS from Full Disk Access by selecting them and clicking "-" at the bottom of the window, wait for them to reappear in the list, and then grant access.
