Two unknown user accounts showing in the security tab

I have two unknown user accounts showing in the security tab. They do not exist under "user accounts" in control panel. I have been unable to delete them and thought they might be part of Comodo firewall or Avast antivirus?

I'm not familiar with how to navigate to the security tab other then right clicking on a file...is there another way? I recently updated both their rights to deny everything in the hopes that might prevent any malicious behavior?

I see SID S-1-5-21-xxxxxxx
Can you post whole SID so xxxxxx as well

Go into registry (regedit) and have a look at key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
expand it. and post the S-1-5-21 sids you see. Make screenshot

Go in explorer to c:\users and rightclick on folder Jef. Change its security so delete both security items there!! They are UNKNOWN so useless!

Everytime I read words like that, I cringe. Until you KNOW the source, I wouldn't assume ANYTHING is useless.

They are security items on C:\Users\Jeff only!! and inhereted by files and folders. Probably from windows mediaplayer sharing (dlna) or old homegroup stuff. As long as system, administrators and Jef himself have full access, I don't see the problem.

But to be honest... you're right with your statement
