What is Complete System Care?

Complete System Care is one of many programs that are categorized as potentially unwanted applications (PUAs), since most people download and install them inadvertently. Complete System Care supposedly optimizes Windows systems and protects them from various threats, however, do not trust or use any programs categorized as PUAs. Additionally, Complete System Care is used to promote another identical program called Advanced Driver Booster.

Complete System Care unwanted application

Complete System Care is advertised as a program that cleans junk, optimizes the Windows registry, eliminates malware, and improves system performance. The free/trial version allows users to scan their systems for various issues, however, to fix them, they must pay for activation. As mentioned, programs categorized as PUAs should not be trusted. They often perform scans that detect false issues. Many users believe that, after activation, the apps will fix detected issues, improve system performance, etc. This is often not the case. It is unknown whether Complete System Care is one of these rogue programs, however, most PUAs have this behavior. Furthermore, set-ups of software such as Complete System Care often include various PUAs and are also used to promote other PUAs such as browser hijackers, adware, and so on. Browser hijacking apps promote fake search engines by changing browser settings. Additionally, they are often used to gather information such as, for example, IP addresses, geolocations, addresses of visited pages, entered search queries, and other details relating to users' browsing habits. Typically, developers share the data with other parties, who might be cyber criminals, and misuse it to generate revenue. Adware is software that serves unwanted, often deceptive ads. When clicked, these ads open dubious websites or run scripts designed to download or install PUAs, potentially malicious apps. Do not use software such as Complete System Care and uninstall all PUAs immediately.

Complete System Care is similar to other programs of this type including, for example, Qbit Optimizer Pro, Auto System Care, and Driver Tuneup. Generally, developers advertise them as useful tools that supposedly optimize systems, update drivers, and so on. Unfortunately, in many cases, these programs do not solve any problems and simply provide fake results.

How did potentially unwanted applications install on my computer?

People often download and install PUAs unintentionally/accidentally. To distribute PUAs, developers use a deceptive marketing method called "bundling". They include unwanted programs into the set-ups of other software that people usually download and install intentionally. Furthermore, they hide offers to download or install additional software in "Custom", "Advanced" and other similar settings. In many cases, people allow unwanted programs to be downloaded and installed together with regular software when they leave the aforementioned settings unchanged. Unwanted downloads and installations can also be caused by clicking deceptive ads, which then run scripts designed to download and install unwanted software.

How to avoid installation of potentially unwanted applications

Do not finish any download or installation process without checking all available "Custom", "Advanced, and other similar settings and dismissing offers to download/install unwanted apps. Download software only from official websites and using direct download links. Do not use third party software downloaders, installers, Peer-to-Peer networks such as torrent clients, eMule, or other such tools/sources. If clicked, many intrusive ads redirect users to dubious websites. Do not click them, especially if they are displayed on dubious websites. Check the list of extensions, add-ons, and plug-ins that are installed on the web browser and remove unwanted, unknown or suspicious apps. Also apply this to programs installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
