What is Cosmos System Care?

Cosmos System Care is another dubious application presented as a high-quality system optimization/cleaning tool. Its appearance suggests that Cosmos System Care is a legitimate and useful application, however, it is likely to infiltrate systems without permission, since developers proliferate it using a deceptive marketing method called "bundling". Therefore, Cosmos System Care is categorized as a potentially unwanted application (PUA).

Cosmos System Care unwanted application

This application supposedly allows users to scan the system and clean various junk files, fix registry entries, and so on. As a rule, Cosmos System Care's free version is only capable of scanning the system, but it is unable to fix other issues located by the scan. Therefore, uses are encouraged to pay for the 'full version'. It is currently unknown whether the Cosmos System Care application is trustworthy. Research shows that many "bundled" system optimization tools are fake. They generate misleading scan results to trick users into purchasing full versions of software that give no real value. Cosmos System Care is probably one of these dubious applications. Therefore, we recommend that you consider uninstalling it. "Bundling" is often used to distribute several unwanted applications (in most cases, adware and browser hijackers) at once. Therefore, Cosmos System Care may not be the only PUA that has infiltrated your system. These rogue applications typically generate intrusive advertisements, cause unwanted redirects, and record personal information. Therefore, uninstall Cosmos System Care and also remove other dubious applications and browser extensions.

The Internet is full of potentially unwanted applications that share many similarities. Most offer 'useful functionality' just to trick users to install. In fact, few provide the functions promised. In most cases, potentially unwanted applications have only one purpose: to generate revenue for the developers. Rather than giving any real value, they cause redirects, deliver ads, and gather information, thereby posing a direct threat to your privacy and Internet browsing safety.

How did potentially unwanted applications install on my computer?

Cosmos System Care is distributed via its official website and "bundling", and thus it is likely to infiltrate systems without permission. "Bundling" is essentially stealth installation of third party software with regular (mostly free) apps. Developers conceal "bundled" applications within "Custom/Advanced" settings (or other sections) of the download/installation processes. Furthermore, many users often rush these procedures and skip steps. This behavior can lead to unwanted installation of third party applications such as Cosmos System Care.

How to avoid installation of potentially unwanted applications?

Select "Custom/Advanced" settings and carefully analyze each window of the download/installation dialogs. Decline offers to download/install third party applications and opt-out of those already included. You are also strongly advised to avoid using third party downloaders/installers and download your programs from official sources only (via direct download links). Developers monetize third party download/installation tools by "bundling" third party applications, and thus these tools should not be used. PUAs are often distributed using intrusive advertisements that redirect to malicious websites and run scripts designed to download/install unwanted apps. Most of these ads seem legitimate, since developers invest many resources into their design. In fact, they redirect to dubious websites (gambling, adult dating, pornography, etc.). As mentioned, most intrusive ads are delivered by adware-type apps. Therefore, if you encounter suspicious redirects, remove dubious applications/browser plug-ins immediately. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
