One System Care is considered to be a system optimization tool which supposedly should protect users and retain healthy PC performance. In reality, this so-called all-in-one computer aid is classified as a potentially unwanted program (PUP)[1] by IT experts due to promotional content and redirects to shady pages it causes.

This alleged PC tool can be called One SystemCare virus because AV engines detect the application as malicious or dangerous.[2] Even the paid version does nothing improving for the machine or its speed and performance. Such registry cleaners are suggested to be dangerous because deleting certain entries can cause crashes and disabled programs.

Even though it is not malicious, it uses less than fair techniques to gain revenue. The primary purpose of the One SystemCare is tricking users into purchasing more useless software and obtaining revenue from commercial content delivered directly to your screen.

This system tool does nothing valuable for the device and can be uninstalled alongside other additional content added without your permission which affects the speed of the system and loads background processes. System issues that fake system tool indicates about are false, and there is no need to purchase any licensed version of the program to remove possible threats.

When inside the system, the One System Care may start showing you continuous warning messages about hundreds of errors and unused files that you should remove from your computer. Of course, some of these files should be eliminated from the system, but we cannot guarantee that by removing one hundred of such data you will be able to see a clear difference in your PC's performance.

Often such tools that claim to improve the performance of the machine involve registry cleaning and other activities that may seem harmless. However, when One System Care deletes allegedly useless files or registry entries it can affect the performance in a negative way or even damage the machine.

Also, One SystemCare virus can try to convince you that you need to install additional programs on your computer or download their latest updates, purchase licensed version. As you may have already understood, most of such pop-up ads are misleading, and you should never click on them since you can be tricked into downloading more PUPs on your system.

Even the full tool with a purchased One System Care license key cannot perform the alleged cleaning process. It only cleans the fake list and claims to have removed all the threats. You pay for the useless application and the system remains infected with the PUP.

Additionally, the rogue tool can initiate silent installations of:

  • browser extensions;
  • toolbars;
  • bookmarks;
  • in-browser tools.

After checking One SystemCare user reviews, it becomes clear that there are hundreds of people who are trying to find the license key. That's because the trial version of this program can only be used for checking the computer's state and finding the issues.

How to prevent from getting system tools

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
