Unknown files and folder

[dfs4]

I get an alert from my firewall defense that 'Systed could not be recognized and it is about to create a new file/folder C:\Windows\System32\Logfiles\WMI\RtBackup\EtwRtmsMpPsSession7.etl' and it goes on to say this happens when a new application or update is installed. I updated windows a few days ago and reinstalled the whole windows. I blocked it a few times but did a google search and the folder seems somewhat genuine windows folder but this particular file is not explained. Should I allow it? I have allowed it a couple times.

That is a log file created by WMI (Windows Management Instrumentation). It's a legit file. Are you using Comodo and the Defense+ is popping up? You can allow it and click the box to remember and it won't pop up any more. Any doubts and you can send the file to Virus Total. A Guy
