MBKWbar is an adware parasite that displays undesirable commercial advertisements in pop-ups using Internet Explorer web browser. This threat doesn't spread by itself and must be manually installed. Once executed, MBKWbar drops its files to a hard disk and modifies the Windows registry, so it could run along with the Internet Explorer.
