How to remove System-Checker (Virus Removal Guide)

System-Checker is a deceptive and intrusive advertisement-supported potentially unwanted program (PUP) and spyware that can cause many problems for computer users. Once System-Checker is installed it will display a tray icon on Windows Task Bar that measures system information. System-Checker may pretend to be published and made by Microsoft. Computer users who find this program installed may experience unwanted browser redirects, pop-up advertisements, and experience a loss in computer speeds and computer functionality.

What is System-Checker?

System-Checker is often promoted as a free program created by Microsoft that can be used to display system information such as CPU and memory data. The program will display a tray icon on Windows Task Bar that will show information when a mouse hovers over the icon. System-Checker is not made by Microsoft and is known to be destructive and intrusive.

System-Checker installs a Layered Service Provider and installs numerous certificates that allow it to access and remotely collect all of your network communication data without your knowledge.

System-Checker is also known to serve ‘targeted’ advertisements to users while they browse the internet. This is a privacy concern because targeted advertisements can only be produced by the adware if it has access to user browsing data, such as  all browsing activities, bookmarks, app data, and browser history. This information is observed and used to generate advertisements it feels users are most likely to click on.

Furthermore, System-Checker bundles with additional unwanted programs, malware, and other possible malicious threats. This means that it might be necessary to uninstall multiple programs from Windows and remove multiple browser add-ons and extensions from Chrome, Firefox, Internet Explorer, and Safari. Many of these programs can not easily be found on a computer system without third-party security software.

System-Checker adware and the additional programs that it bundles with also manufacture new tasks and change existing Windows start-up settings in order to run every time the operating system starts and remain enabled if disabled by the user. Programs and browser attachments that may arrive with this deceptive piece of adware can also cause other issues for computer and internet users aside from pop-up advertisements, including browser redirections and a loss in computer functionality and internet connectivity. Furthermore, if System-Checker is manually removed, it is possibly that the adware or another one in its place will return before a week has passed.

How did System-Checker get on my computer?

System-Checker adware is usually contracted without consent or knowledge of the computer user alongside third-party programs and files, such as freeware, shareware, torrent files, and other free downloadable content. The potentially unwanted programs and files that deliver the adware can be introduced to a computer system and affected internet browsers with or without user authorization.

Computer and internet users who seek to download and install free programs and files online may be presented with an opportunity to accept or decline a ‘custom’ offer to install System-Checker adware and other programs during the setup and installation process. However, the request to decline System-Checker adware from installing is often presented in a very confusing manner. In some cases, the download manager may completely ignore the user request to decline System-Checker from installing and the adware will install against user consent and knowledge.
