PCKeeper is advertised as an optimization services package featuring a set of software utilities for Windows OS owned by Essentware S.A. (company based in Bratislava, Slovakia).

The first lawsuit, filed in Illinois, alleges that "Contrary to ZeoBIT's marketing and in-software representations, however, neither the free trial nor the full registered versions of MacKeeper perform any credible diagnostic testing of a user's Mac.

Instead, ZeoBIT intentionally designed MacKeeper to invariably and ominously report that the consumer's Mac needs repair and is at-risk due to harmful errors, privacy threats, and other problems, regardless of the computer's actual condition.

"[citation needed] The second complaint, filed by Holly Yencha of Pennsylvania, alleges that the free starter version of MacKeeper identifies harmless programs as "critical" problems.

The complaint claims that "under MacKeeper's reporting algorithm, even brand new computers are in 'critical' condition and require repair by purchasing the full version.

PCKeeper Live offers 13 different PC services in 4 categories: Human Assistance (Find & Fix, Geek on Demand, Live Support), Security (Anti-Theft, Data Hider, Shredder, Files Recovery), Cleaning (Disk Cleaner, Disk Explorer, Duplicates Finder, Uninstaller) and Optimization (Context Menu Manager, Startup Manager).

and "Kromtech's 24/7 support is what elevates PCKeeper Live from an overpriced utility program to a tool that even a non-geek can use to optimize his/her computer.

However, it scored poorly in independent lab testing and the chat based support was "soured by the fact that they served me misinformation."
