How can I unblock Facebook?

Question

I blocked Facebook following the mentioned steps (Add site, Restart Broowser, Clear Cache, Turn off the antivirus). When I tried to remove the Facebook site from the list, there is an error message saying "Unable to update system configuration to reflect the changes. This is probably caused by a security program, such as antivirus or anti-spyware program or you don't have sufficient user level". I can't access Facebook anymore. How can I fix this?

Answer 1

In order to fix the issue, temporarily disable all your antivirus and security programs and make sure you launch Any Weblock from an Administrator account. If it doesn't help, open the application, click the Roll back button and select an old backup from the list. If it doesn't work, uninstall the application (Control Panel > Uninstall a program) and run CCleaner or Glary Utilities.
