The file gkh.dll, known as Sunbelt Kerio Firewall Keyboard Hook, belongs to software Sunbelt Personal Firewall by Sunbelt Software. This security application was originally known as Kerio Personal Firewall, which is a desktop personal firewall originally developed by Kerio Technologies and acquired by Sunbelt in December 2005. It protects the computer from external and internal attacks from other computers. It helps control how computers share information with other computers through the Internet or a local network, and is especially useful for laptop computers that are easier to compromise because of built-in wireless access. The firewall examines information that tries to enter a computer from an outside source, and determines if the information is safe or harmful. The Sunbelt Personal Firewall was discontinued effective May 23, 2011, and existing users of the firewall with current subscriptions were offered free download of the VIPRE Antivirus Premium from Sunbelt.
