How can I prevent third parties from making changes to the Parental Control settings in Dr.Web for Windows?
Select Start → Settings.
Go to the Accounts section.
Click on Family and other users.
Make sure the user accounts for which you have imposed the restrictions do not have administrator privileges.
If necessary, change their account type from Administrator to Standard.
Also make sure that a reliable password is specified for your Administrator account. If no password is specified, press Alt + Ctrl + Delete, and click Change password. Enter the new password in the New password and Confirm new password fields. Then press OK.
