I've been using for a while a comprehensive security product for my PC (Kaspersky pure): The parental control pane is now listing three new users that I did not create (it's a home computer and I'm the sole administrator). These users do not appear on the Windows Control Panel!
- How can I remove/block them? (For now, I use parental control to fully block their access to the internet)
- How can I avoid further intrusions?
