Does Windows Defender create a batch file?

Hi there, I am on Windows 11 an Defender did detect some malware during an installation. 
The files have been blocked and quarantined, a deep scan did not find any more issues. 

But I had a weired explorer behaviour after restarting - explorer exe did stop and restart. I realized the is a bactch file called securitycenter.bat in the autostart folder. The batch stops and restarts explorer. It was created right at the time defender did notice about the malware. 
I checked explorer exe. There is only one on the system and it seems to be the correct one (signed by Microsoft).

Any ideas?
