How to remove Qbit System Care
Written by Tomas Meskauskas on (updated)
What is Qbit System Care?
Qbit System Care (or Qbit ~System Care) is a potentially unwanted application (PUA) designed to clean, optimize, and speed up Windows computers. It is categorized as a PUA due to the method that developers use to distribute it - they include Qbit System Care into the set-ups of other programs.
Typically, people agree with offers to download and/or install this additional software inadvertently or unintentionally. Research shows that Qbit System Care advertises another PUA called Driver Updater.
Like many other PUAs, Qbit System Care allows users to scan their systems for malware (or other unwanted software), startup, and other items that could impact system startup time and overall system performance. In fact, none can be removed without purchasing (activating) Qbit System Care. PUAs often detect fake issues.
They trick users into believing that their computers could run faster, without errors, etc. if they fix detected issues using the activated version. Generally, these versions are not free. It is unknown whether Qbit System Care generates fake results, however, many PUAs have this behavior.
Qbit System might also be distributed together with other PUAs including, for example, browser hijackers and adware-type apps. In this way, they often try to trick people into downloading and/or installing more than one PUA at once. Browser hijacking apps change browser settings to promote dubious websites, typically fake search engines.
Additionally, they gather information relating to users' browsing habits including, for instance, IP addresses, URLs of visited websites, entered search queries, geolocations, and other data of this kind. Developers send this data to other people (potentially cyber criminals) who misuse it to generate revenue.
Adware is software that displays advertisements. When installed, it feeds users with coupons, banners, surveys, pop-ups, and so on. Generally, these conceal underlying content of visited websites and, if clicked, cause redirects to dubious web pages or run scripts that download and/or install unwanted software.
In summary, apps of this type might cause problems with browsing safety, privacy, or even lead to identity theft. Software such as Qbit System Care should never be trusted. We recommend that you remove this software and any other PUAs installed on the operating system and/or browser.

How did potentially unwanted applications install on my computer?
People generally download and install PUAs (including Qbit System Care) unintentionally when they are included into the set-ups of other programs. This deceptive distribution method is called "bundling". Information about these additionally-included apps is hidden in "Custom", "Advanced" and other similar options of the download or installation set-ups.
These apps are thus downloaded and/or installed when users fail to check these settings.
By leaving them unchanged, they unintentionally allow PUAs to be downloaded and/or installed together with regular software. In some cases, unwanted downloads and installations are caused through deceptive ads. When clicked, some can execute scripts that download or install PUAs.
How to avoid installation of potentially unwanted applications
Download software from official websites and avoid downloading or installing through unofficial websites, third party downloaders, installers, Peer-to-Peer networks such as torrent clients, eMule, and so on. Check "Advanced", "Custom", and other similar settings of any download/installation setup.
They often contain offers to download or install additional software. Avoid clicking suspicious, intrusive ads, since they usually redirect to untrustworthy websites or cause unwanted downloads and installations. In most cases, ads of this kind are displayed on web pages relating to gambling, adult dating, pornography, and so on.
Browsers often open dubious pages and/or display ads due to PUAs already installed on browsers or computers. In these cases, remove all unwanted, unknown or suspicious extensions, add-ons and plug ins installed on the browser, and programs of this kind installed on the operating system.
If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
