How to remove One System Care (Virus Removal Guide)

One System Care (also found as One System Care virus, OneSystemCare, One SystemCare) is a potentially unwanted program (PUP) that is known to utilize various questionable marketing practices in order to get users to download and install the program. The One System Care program is usually bundled with other unwanted programs, adware, and malware.

One System Care can also be manually downloaded; However, the program is primarily packed inside the installers of third-party unwanted programs and malware. The program will automatically install in the background and will run every times Windows starts. There is no option to disable this program from running once Windows starts.

What is One System Care?

One System Care by OneSystemCare (or other publisher) is promoted as a free Windows Optimizer and Cleaning program that can clean up junk files, fix system related issues, Com and Active X issues, and user related issues, as well as boost computer performance.

Alike other free deceptive and intrusive system optimization and cleaning programs One System Care offers no realistic value to a computer system. One System Care claims to be free, but the program will not fix issues it detects unless users purchase or register the full version of the product. The internet security community mostly claims that possible One System Care malware is essentially “snake oil.” It’s a pointless program according to multiple security vendors.

One System Care is also known to introduce and bundle with multiple programs (such as Max Computer Cleaner, Zombie News, Block Operator, SmartWeb, Infonaut, Ge-Force, Consumer Input, and others) and download multiple files once it has been contracted. Since potential One System Care malware primarily bundles with additional unwanted programs, malware, and other possible malicious threats it will be necessary to uninstall multiple programs from Windows and remove multiple browser add-ons and extensions from Chrome, Firefox, Internet Explorer, and Safari. Many of these programs can not easily be found on a computer system without third-party security software.

One System Care adware and the additional programs that it bundles with also manufacture new tasks and change existing Windows start-up settings in order to run every time the operating system starts and remain enabled if disabled by the user. Programs and browser attachments that may arrive with this deceptive piece of adware can also cause other issues for computer and internet users aside from pop-up advertisements, including browser redirections and a loss in computer functionality and internet connectivity. Furthermore, if One System Care is manually removed, it is possibly that the adware or another one in its place will return before a week has passed.

How did One System Care get on my computer?

One System Care adware is usually contracted without consent or knowledge of the computer user alongside third-party programs and files, such as freeware, shareware, torrent files, and other free downloadable content. The potentially unwanted programs and files that deliver the adware can be introduced to a computer system and affected internet browsers with or without user authorization.

Computer and internet users who seek to download and install free programs and files online may be presented with an opportunity to accept or decline a ‘custom’ offer to install One System Care adware and other programs during the setup and installation process. However, the request to decline One System Care adware from installing is often presented in a very confusing manner. In some cases, the download manager may completely ignore the user request to decline One System Care from installing and the adware will install against user consent and knowledge.
