Remove One SystemCare (Permanent Removal Guide)

This page is here to help you remove One SystemCare. This One SystemCare removal guide is suitable for all Windows versions.

What One SystemCare is

This is one in a vast deluge of Potentially Unwanted Programs that an increasing number of users are being subjected to. If detected, clean One SystemCare from your computer. It claims to be a system optimizer that operates by cleaning a system’s registry and identifying troublesome or threatening files and promote faster operating speeds. It finds its way onto a computer as part of a bundle of downloaded freeware. This PUP is added (hidden) by download clients (third parties who work for software companies to distribute in-demand freeware samples to the public). This is often done in a slight-of-hand manner and many unsuspecting p.c users will not detect the pest in the parcel of software. At best it’s appearance is inconvenient for those with the technical experience and patience to rid their p.c of it; for others who fall victim to it, it could be seen as ‘legitimized’ extortion by playing on a created sense of insecurity.

How One SystemCare operates

Once erroneously installed on a system, One SystemCare independently initiates a full system scan with Windows start-up, where it establishes roots. Even if disabled, it will open again at your next start-up. At random times, an insistent pop-up will inform errors of varying degrees have been detected and offer to ‘Clean Now’. IF THIS HAPPENS DO NOT CLICK! If you do, then you will be requested to purchase the full package in order to deal with the threats – the implication being that without the full service your computer is doomed. Uninstall One SystemCare immediately. If not, you will experience on-going, increased threat warnings. And disruption.

A company may appear legitimate with an official, functioning website where the full package is available to buy. This is something that often misleads potential customers into buying dubious – or at best – substandard software. If the home ‘site looks professionally designed and claims to offer customer support, many people can be deceived. It is interesting to note that One System Care is reported by infection logging to be most prevalent at present time in central America, central Europe and parts of Africa, though hardly registers in North America. Given that the web is world-wide, this suggests that certain demographic groups could be more susceptible to different types of devious presentation and quicker to click and buy a questionable product. Or perhaps these people are more vulnerable to the supposed threats cleverly presented to them by such products.

How One SystemCare performs in tests

It’s been written that previous scans undertaken included numbers of files that were damaged, or not in use – though these were certainly not a hazard. This was to boost the threat ‘warning’ and sense of urgency about ‘dangerous’ elements on drives. If you pay up for the full version and perform a clean-up, certainly these files will be deleted though this will probably not ‘optimize’ your systems performance in any noticeable way. The users testing the scan and full-package clean-up also found that random benign or useful files and programs were deleted in the process. And as the program runs in the background of Windows, it has been seen to actually slow running speeds, contrary to its optimization claims. If you find yourself with this program, delete One SystemCare to save even greater potential problems…

Alternatively, get a good security program and clean it out – this will also save a possible revisit of this or similar infections. If this is program is not strictly malicious by itself, it is definitely not fit for purpose. Rather than being classified as a PUP, it should be termed a TUP – a Totally Unwanted Program. So – if you’re unlucky enough to be offered ‘optimization’ by these people – tell them you don’t care for their services, and operate – cure One SystemCare now!
