Account Unknown RRS feed

  • Question

  • Recently, under the security tab when I press properties of a file, I have started to see that an Account Unknown has access to my files.

    I'm not sure if it's a hacker or not.
    Because I have always had two user accounts on my computer.
    And now I see that 5 "users" have access to it.

    SYSTEM (this one is okay)
    My account
    2nd user account
    Account Unknown (S-1-5-21-3938085426-2355908419-373501850...)

    Can you please help? And tell me what that account unnknown is.

  • This indicates that the SID S-1-5-21-3938085426-2355908419-373501850... cannot be resolved to an existing account in the local or trusted domain/forest.

    This might be the result of that account being deleted or an issue with trust relationship
