unknown user

Hello everyone, I have an unusual problem and don't know if I'm in the right thread.

When I log off, I get a new user shows up at login as eqwkyvqyt, anyone know what would cause this? I deleted the user once already and it came back up again.

Eset virus scans negative.

Thanks in advance for your help.
