What is System-Checker?

Developed by MC Software Inc, System-Checker is a deceptive application that is not recommended using. However, be aware that neither the program itself nor the service it offers, which is to allow users to monitor various system-related information, including CPU, memory, and system load, are harmful. However, System-Checker is sponsored by third parties and may also try to promote third-parties by delivering sponsored content while you are browsing. Computer’s security experts have already labeled it as an adware and a potentially unwanted program (PUP), whereas developers of reputable anti-malwares have inserted PUP.System-Checker and adware.System-Checker to the virus databases. The majority of activities that System-Checker virus is set to implement to marketing purposes are initiated behind user’s back. For example, it may continuously connect to the Internet in order to download updates (or maybe other third-party apps), step-by-step affect your computer’s security system in order to increase vulnerabilities or may run various processes (e.g. two System-Checker.exe in Task Manager) in order to burden the system and slow it down. Even more, it may hijack each of your web browser (Google Chrome, Mozilla Firefox, Internet Explorer, Safari), modify settings and install cookies on each of them. Consequently, it may continuously track you and accumulate non-personal data about your browsing habits. However, there is one prominent sign indicating that this adware hides in your computer. Once installed, it may start generating System-Checker Ads on every website that you visit. They may be customized according to your preferences, so it’s not surprising that most of them may seem very interesting. However, keep in mind that each of the ‘Ads by System-Checker’ are developed and monitored by third-parties, which means that they may redirect you both to safe and suspicious websites. In case you want to get rid of this adware now, we recommend using Webroot SecureAnywhere AntiVirus (Mac OS X) or Reimage (Windows OS X).

How can System-Checker hijack my computer?

In order to prevent System-Checker redirects, it’s enough to ignore commercial messages that it may initiate. However, in order to prevent infiltration of this adware, it’s not enough to stay away from its official website (system-checker(dot)com) and not download it manually. That’s because System Checker adware is also distributed via software packages. Generally speaking, the majority of adwares are distributed via other freewares and sharewares as ‘optional downloads’. Therefore, in order to keep your computer safe, first of all you should avoid installing free programs without a purpose. If you decide to install one, make sure that you look for its official website or another reliable download source. Besides, read EULA, Privacy Policy and other relevant information about it. Finally, opt for Advanced or Custom installation and carefully check everything step-by-step. If you notice a check box claiming that you agree to install System-Checker add-on on your computer, make sure that you opt out of it.

System-Checker removal is not a difficult task. However, if you decide to uninstall it manually, we recommend checking your machine with a reputable anti-spyware in order to get rid of other suspicious entries from the system.
