If you are using Malwarebytes Management Console version 126.96.36.19914, you may notice computers that use a proxy will not update after editing a policy.
This occurs due to a bug where the proxy server settings are not retained when you edit a policy.
To prevent this from happening, please make sure to click the Updater tab, and then the Proxy Settings button on the policy. You do not need to make any changes to the Proxy settings, just view them. Once you have viewed the settings, you may close the settings and continue making any policy changes needed.
