One System Care removal instructions

What is One System Care?

One System Care is presented as an application that helps to clean computer systems of various junk files - "OneSystemCare fully cares for your laptop and computer to protect it from unnecessary junk files and recurring issues by thoroughly scanning and inspecting its many components." This functionality may seem legitimate and useful, however, One System Care is classed as a potentially unwanted program (PUP). The reasons for these negative associations are stealth installation and tracking of web browsing activity.

One System Care adware

After system infiltration, One System Care gathers various Internet browsing-related information including IP addresses, websites visited, pages viewed, search queries - these are just some examples from long list of data types recorded by this PUP. Some of this collected information will be personally identifiable - the developers of One System Care share this with third party companies who often misuse information to generate revenue. This behavior can lead to serious privacy issues or even identity theft. Therefore, the presence of One System Care on your system can lead to serious privacy issues or even identity theft. This behavior is very common for various adware-type applications. As well as tracking users' browsing activity, these applications often cause unwanted browser redirects and display intrusive online advertisements, thereby significantly diminishing the Internet browsing experience. We strongly advise you to uninstall One System Care immediately.

One System Care has similar characteristics to dozens of other deceptive applications also claiming to enhance the Internet browsing experience including, for example, PepperZipResults Hub, and TheBrowser. All falsely promise to provide a number of useful features - these are attempts by PUPs to trick users to install. Bear in mind that all adware is designed to generate revenue for the developers. Rather than providing any real value for users, apps such as One System Care display intrusive online advertisements and track Internet browsing activity.

How did One System Care install on my computer?

Research shows that many users install this application inadvertently. This is due to deceptive software marketing method called 'bundling' (stealth installation of third party apps with regular software/apps). The developers know that many users do not express enough caution when downloading and installing software - they rush these processes and skip most/all steps. Therefore, bundled software is often hidden within the 'Custom' or 'Advanced' settings. By skipping this section, users expose their systems to risk of infection and put their privacy at risk.

How to avoid installation of potentially unwanted applications?

The key to computer safety is caution. Do not rush the download or installation processes. Bundled software (that should be cancelled) is mostly concealed and, therefore, it is important to closely analyze each step of the download and installation procedures.
