"unknown Users" are listed in Properties/Security of a folder.
PROBLEM: "unknown Users" are listed in Properties/Security of a folder.
I have Windows 7, 64-bit.
The Properties/Security box of my "C:\Users\[my name]" folder lists two Users called
"Account Unknown (S-1-5-21-879640176-2077098734-2292519611-1001)"
and, "Home Users", in addition to the legitimate Users "SYSTEM", "Administrators", and "[my name]".
After deleting the computer's Limited Acct, the 2 Users are still listed.
"S-1-5-21-879640176-2077098734-2292519611-1001" is not found by the Yahoo Search Engine. The Windows folder-specific search engine for "C:" and for "Users" searches essentially indefinitely. That for the folder named after myself finds nothing.
Especially regarding "S-...", is this caused by malware ? Would deleting either or both of these Users cause harm ?
Thanks.
