Developers of System Health Checker do not provide much information about it, and our specialists could not find more about it either. There is only one sentence provided in the program description: “Monitor your system health and prevent before too late.” Judging from this short description, it should help users to keep their PCs healthy, but we can assure you that it does not act beneficially at the time of writing. Actually, it does not do anything at all, so, according to our specialists, it might be very buggy, or it is still in development. Theoretically, it might be updated in the future and start acting properly, but, unfortunately, we cannot promise that it will become a useful program, so we do not suggest keeping it installed either.

Potentially unwanted programs, including System Health Checker, often travel in software bundles with third-party software. It is very likely that you have installed a software bundle on your computer too if you do not know anything about the installation of this browser extension. Unfortunately, this might also mean that you have allowed other untrustworthy programs to sneak onto your computer too – they could have been distributed in the same software bundle together with System Health Checker.
