Pop up message after restoring storage from Time Machine

Today I have erased data from my hard drive using disk Utility - I had an incident of clicking a link in a possible phising email and wanted to be sure that my iMac is clean of malware. Afterwards I have restored my Disk using Time Machine copy (stored on an external hard drive and made couple months before, so should be Safe).

everything seemed fine, but after restoring data and rebooting, a message popped up from system settings that „system extension signed by fumihiko takayama has been blocked”. I did some Google searching and apparently something similar happened to people who installed an app called Karabiner. However, I do not have this app.

Is it possible that its some kind of malware?

iMac 24″, macOS 14.5

I decided to solve the problem in a different way:

Wiped the Disk again
restored the Disk using Time Machine, but this time I did not restore the Apps (just Files etc). Once the mac rebooted there was no pop up message.

thank you for the help though.

It depends.

First, a disclaimer: As a rule, I never install third party system extensions on any of my Macs, because I need them to work reliably. Moreover, I don't know how to uninstall them. I do know that removing those third party system extensions can be difficult.

Next: If you want to track down the likely culprits, EtreCheck is likely to help. Instructions are here: How to use the Add Text Feature When Posting Large Amounts of Text, i.e. an Etrecheck Report - Apple Community.

Follow those instructions. Please read them with care, and post that report in a reply to this Discussion. If I can help, I will.

i have seen this. But does it explain why this message showed up on my mac, even though I have never downloaded this app? (Bear with me - I am not a native english speaker, nor an IT specialist, which makes it hard to understand exactly what they say in this article 😅)
