Zeobit LLC (stylized ZeoBIT) was a technology and software company formed in 2009 by CEO Slava Kolomiychuk and located in Sunnyvale, California. The company specialized in computer security software and internet security. As of December 2016, it is no longer in business. Zeobit is best known for the bundled utility software MacKeeper. The software has received mixed reviews with reviewers being very divided as to the effectiveness of the product. History Zeobit LLC was incorporated in September 2009 in the US State of California by Slava Kolomiychuk. Zeobit has a management headquarters in Sunnyvale, California and partnership offices in Europe and Asia that house developers and the customer support. In March 2010 their first product, MacKeeper (for macOS) was released and in September 2010 PCKeeper (for Microsoft Windows) was released. On May 13, 2010, the first beta version of MacKeeper, version 0.8, was released. On October 4, 2010, PCKeeper (MacKeeper's equivalent for Windows PCs) (version 1.1.48) was released. On October 26, 2010, Zeobit released MacKeeper 1.0. On January 30, 2012, MacKeeper 2.0 was released with updates in security, data control, cleaning and optimization. In 2014, a Pennsylvania woman filed a class action lawsuit against Zeobit LLC, claiming that the company's computer security program identifies problems that don't exist and generates false error messages to scare users into purchasing an upgrade. (see Holly Yencha, et al. v. Zeobit LLC, Case No. 2:13-cv-00578, in the U.S. District Court for the Western District of Pennsylvania.) According to the complaint filed in US District court, "Once installed, MacKeeper prompts the user to conduct a diagnostic scan", the MacKeeper class action lawsuit says. "This scan purportedly detects errors that lead to the problems identified in Zeobit's marketing materials (i.e., performance issues, security and privacy threats)—problems that MacKeeper is supposedly designed to fix." However, the Zeobit class action lawsuit alleges that after the diagnostic scan is completed, MacKeeper reports that it identified thousands of issues that cause the computer to be in "critical" condition. While the trial version of MacKeeper purports to "fix" a limited number of the issues, customers are encouraged to purchase a full, registered version of the security software to fully repair the computer. Yencha alleges that neither the free trial nor the full versions of MacKeeper perform reliable diagnostic testing of the computer. "Instead, Zeobit intentionally designed MacKeeper to invariably and ominously report that a user's Mac needs repair and is at-risk
