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)...It includes 2 separate products for Windows: PCKeeper Live and PCKeeper Antivirus.
Two class action lawsuits have been filed against Kromtech for the Mac OS version of PCKeeper, MacKeeper. 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.
There are numerous programs which purport to improve system performance, make repairs and tune up a computer
. Many of them include such features as a registry cleaner, registry optimizer, disk optimizer, etc
. Some of these programs even incorporate optimization and registry cleaning features alongside anti-malware capabilities. These registry cleaners and optimizers claim to speed up your computer by finding and removing orphaned and corrupt registry entries that are responsible for slowing down system performance. There is no statistical evidence
to back such claims. Advertisements to do so are borderline scams
intended to goad users into using an unnecessary and potential dangerous product. I would not trust any results
such programs detect as problematic or needing repair nor recommend using the options to fix them.
Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons.
Why you should not use Registry Cleaners and Optimization Tools
This applies to any registry cleaning/optimizing software suite which includes anti-virus/anti-malware protection.
