What is Qbit System Care?

Qbit System Care (or Qbit ~System Care) is a potentially unwanted application (PUA) which supposed to clean, optimize and speed up Windows computers. It is categorized as PUA because of the method that its developers use to distribute it - they include Qbit System Care in setups of other programs. Typically, people agree with offers to download and/or install additional software inadvertently/unintentionally. Research shows that Qbit System Care is designed to advertise another PUA called Driver Updater.

Qbit ~System Care unwanted application

Like many other PUAs Qbit System Care allows its users to scan their systems for malware (or other unwanted software), startup and other items that may impact system startup time and overall system performance. However, none of them can be removed without purchasing (activating) Qbit System Care. The problem is that PUAs often detect fake issues. Simply said, they are designed to trick users into thinking that their computers could run faster, without errors, etc., if they would fix detected issues using the activated version. As a rule, those versions are not free. It is unknown whether Qbit System Care generates fake results, however, many PUAs do. Also, it is very likely that Qbit System is distributed together with other PUAs, for example, browser hijackers and adware-type apps. In other words, they often try to trick people into downloading and/or installing more than one PUA at once. Browser hijackers are apps that change browser's settings to promote questionable websites, typically, fake search engines. Additionally, they gather information related to user's browsing habits. For instance, IP addresses, URLs of visited websites, entered search queries, geolocations, and other data of this kind. Their developers send it to other people (potentially cyber criminals) who misuse it to generate revenue. Adware is type of software that is designed to display advertisements. Typically, installed adware feeds users with coupons, banners, surveys, pop-ups, and so on. As a rule, these adds cover contents of visited websites and, if clicked, cause redirects to shady pages, or run scripts that download and/or install unwanted software. To sum up, apps of this type might cause problems with browsing safety, privacy or even lead to identity theft. Software like Qbit System Care should not be trusted, we recommend to uninstall it and to the same with other PUAs that are (if are) installed on the operating system and/or browser.

Most PUAs are presented as useful and legitimate. However, quite often apps that are distributed through setups of other programs do not provide any real value and often cause various problems. More examples of programs that are similar to Qbit System Care are PC Power Plus, Quick PC Tuneup and Complete System Care.

How did potentially unwanted applications install on my computer?

As we mentioned in the introduction, most of the times people download and install PUAs (including Qbit System Care) unintentionally. Very often they are being included in setups of other programs, this deceptive distribution method is called "bundling". As a rule, information about additionally included apps is hidden in "Custom", "Advanced" and other similar options of download or installation setups. These apps get downloaded and/or installed when users do not check those settings. By leaving them unchanged they unintentionally allow various PUAs to be downloaded and/or installed together with a desired software by themselves. In some cases undesired downloads and installations can be caused through deceptive ads too. When clicked, some ads execute scripts that download or even install one or another PUA.

How to avoid installation of potentially unwanted applications?

In order to avoid unwanted downloads and installations we advise to download software from official websites, and avoid downloading (or installing) it through unofficial websites, various third party downloaders, installers, Peer-to-Peer networks like torrent clients, eMule, and so on. Also, it is important to check "Advanced", "Custom" and other similar settings of any download or installation setup. They often contain offers to download or install additional software. We also recommend to avoid clicking suspicious, intrusive ads. They usually redirect people to untrustworthy websites or cause unwanted downloads, installations. In most cases ads of this kind are displayed on pages related to gambling, adult dating, pornography, and so on. Quite often browsers open shady pages and/or display ads because there is some PUA already installed on them (or computers). In such cases it is required to remove all unwanted, unknown or suspicious extensions, add-ons or plug ins that are installed on a browser and/or programs of this kind that are installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
