Microsoft says:

Omnitech Support, a division of Customer Focus Services, is charged with misusing Microsoft's name, registered trademarks and service marks in connection with the provision of phony tech support services. Omnitech utilized the Microsoft trademarks and service marks to enhance their credentials and confuse customers about their affiliation with Microsoft. Omnitech then used their enhanced credibility to convince consumers that their personal computers are infected with malware in order to sell them unnecessary security services to clean their computers.
