How secure is Surfblocker, can it be bypassed?

Surfblocker can not be bypassed or disabled by most regular users, however users with highly advanced computer skills might attempt to break the software.

There are several steps you can take to prevent even advanced users from disabling Surfblocker.

• You should set regular user accounts to limited accounts (not administrator account) and allow your users to log in as non-administrators only.
• Advanced users might disable the service, if your system policy allows them to do so. To achieve top security, you should block the management console for non-administrator users. There is a method of disabling Service Management console. Here you can find more info (you will have to edit the Windows registry).
