Although seemingly legitimatе, One System Care appears to be a rogue system optimizer, tricking users into believing their system needs to be fixed and cleaned from junk files. The fake service also asks for payment or else, it claims, it cannot finish the clean-up process. Experts advice to ignore messages by One System Care and find a way to remove the PUP (potentially unwanted program) completely, instead.
One System Care Description
One System Care is technically not a virus, but since it exhibits some malicious traits, security experts classify it as a PUP and a rogue optimizer program. It has rootkit capabilities enabling it to hook deep into the system making it hard to detect by some anti-malware programs.
The PUP enters your system without your consent and displays warning messages stating that it has detected some errors. Then, the message promises to fix them but it requires you to make a payment upfront for this service. Many inexperienced users do transfer money as requested but nothing happens afterwards, as the “detected” errors have never been there on the first place.
The Windows Registry
The Windows Registry is a database on your system that stores thousands of Windows entries. Often, the registry is cluttered with outdated entries due to an uninstalled program that has left some components behind, for example. Therefore, it is sometimes recommended to clean the Windows registry from unnecessary entries. The registry cleaner, however, is free of charge, unlike One System Care.
One System Care may delete working and necessary entries which will result in the malfunctioning of certain programs. And, it may delete an insignificant number of entries which will not improve the system performance at all.
In short, One System Care is not capable of improving your computer performance, and may even cause some of your programs to crash.
How Does One System Care Enter Your PC?
As a PUP, One System Care may infiltrate your system bundled with freeware you download from the Web. Some of the free programs One System Care is known to be bundled with are:
- Max Computer Cleaner
- Zombie News
- Block Operator
- Consumer Input
Thus, to protect your system from unwanted programs and threats, you must opt for custom installation. That means to always disable the bundling option and other settings and features you are not familiar with. Also, avoid accepting the “recommended” or default installation.
How to Remove One System Care?
Some anti-virus programs may not be able to detect the PUP due to its rootkit capabilities. We, therefore, recommend you to remove it by using a powerful and well-trusted anti-malware tool. It will perform a full system scan to detect all malicious components and then it will remove them permanently from your computer. Also, it will continue to protect your PC from future threats from the Web.
