Do I need One System Care?

One System Care is presented as an “all-in-one PC Aid”. This title suggests that this program can be used for protecting computer and increasing the quality of its performance by removing junk files and other useless components. However, we do NOT recommend trusting such well-written phrases because One System Care Cleanup console has already been added to a “potentially unwanted program” category. When inside and active, this application may start showing you continuous warning messages about hundreds of errors and leftover 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 files you will be able to see a clear difference i your PC’s performance. Also, One System Care virus can try to convince you that you need to install additional programs on your computer or download their latest updates. As you may have already understood, the most of such pop-up ads are misleading and you should never click them. We would like to recommend you ignoring such offers as clicking them may lead you into downloading other PUPs to your PC system.

After checking the Internet, it becomes clear that there are hundreds of people who are trying to find the One System Care license key. That’s because the trial version of this program can only be used for checking computer’s state and finding the issues. However, as we have already mentioned, One System Care may show you exaggerated scan reports that are supposed to lead people into believing that they must purchase the licensed version of this program. Please, do NOT do this! These are lots of similar programs that can be used for free! If you have just noticed one system care.exe or similar processes in your Task manager, you should waste no time and scan your computer for this PUP. It might that you installed it in a bundle with other program. This distribution technique is known as “bundling”. To stay safe, you should follow our installation tips that are given in the next paragraph of this post. If you are looking for One System Care removal tool, we recommend you installing Reimage.

How can One System Care be installed on my computer?

One System Care is very similar to Total System Care, System Speed Up, System Optimizer Pro and many others. Usually, such and similar programs have official websites and can be downloaded from these sites. However, these websites promote only trial versions of these programs suspicious third parties may decide to distribute them using unfair techniques, such as spam messages or fake software update alerts. Nevertheless, the most common distribution technique is known as ‘bundling’, which is closely related to suspicious third parties. We have already mentioned in the previous section that it may be promoted via installers provided on the popular download websites. Usually, this program is installed on Windows 8 but is also compatible with other types of Windows. If you want to keep your computer away from this tool, you have to remember several things:

  • Always select Advanced/Custom installation;
  • NEVER click the Next button before reading the terms;
  • Follow everything carefully and opt out of additional tools (unmark ticks that are already marked for you).

This way, you should prevent unconscious installation of System Optimizer Pro malware and other suspicious apps.
