User's image

I started the scan with MS Safety Scanner, it took about 24 hours to complete the full scan.

During the scan, I can see that it shows about 250 infected files. However, the result, shows that everything is correct, see below.

Is it normal or a limitation of the tool?

    No, if you trust this file and allow it, then Microsoft Defender will only ignore this file and it will detect and remove other .exe files if they are being detect as malware. In case you run scan and it shows everything is fine and only mark this file as allowed (which you did), then you are good to protected.
    If you believe the .exe is safe, you may submit it to Microsoft as incorrect detection, so they could check and if it consider as safe, then remove it from detection:

    This is a known issue that during scan, it will find files which is suspicious of being malware , however as scan goes on and check those files, it will find out they are safe. The main result is the final one and if it shows you are safe, then you are good to go and you may ignore the message during scan.
    In case, you are suspect of malware infection, you may run scan with Microsoft Defender Offline too:
