What is System Health Checker virus?

System Health Checker – a potentially dangerous browser extension that is promoted on bogus sites

System Health Checker is a rough browser extension[1] that is compatible only with Google Chrome web browser. It is presented as a useful tool that helps to ensure that computer’s system is working properly. However, it has nothing in common with protecting your device. It is a potentially unwanted program (PUP)[2] that might cause undesired changes in the browser. For instance, it may change your homepage and default search engine to Yahoo Search. Switching back to Google or another search provider may be complicated. System Health Checker browser extension does not have a visible icon on the toolbar. Thus, you cannot simply deactivate it. What is more, this suspicious program prevents you from accessing Chrome’s extensions. If you try to do that, you will be redirected to chrome://apps/ page. Indeed, manual System Health Checker removal might be complicated. For this reason, we recommend going for automatic elimination option and getting rid of this PUP with the help of reputable anti-malware program, such as ReimageIntego. It detects and deletes the hijacker, as well as other unwanted applications that might be hiding on the system.

The image of System Health Checker virus

The so-called System Health Checker virus is distributed via suspicious websites that trigger push notifications and asks to install this add-on in order to leave the site. The reason why you end up on such website is adware infection. The adware might have sneaked into a computer with the help of freeware and started initiating redirects to misleading sites. However, if you found yourself on the Internet site that asks to install an unknown extension, you should close Chrome (or tab) immediately. Sometimes these websites disable close button, so you should force quit the browser. Clicking any other provided buttons, such as “Add Extension, “OK” or “Cancel” may lead to the installation of System Health Checker. The main purpose of this extension is unknown. However, it is suspected to be capable of tracking data or distributing potentially dangerous programs. Thus, if you suffer from redirects to suspicious sites that aggressively asks to install a browser extension, you should take care of your computer’s state. Do not wait until you accidentally install this suspicious app. However, if you already downloaded it, you need to remove System Health Checker ASAP in order to avoid possible cyber threats.

The tricky methods of PUP distribution

As we already mentioned, System Health Checker spreads via rough websites that deliver a pop up informing about a necessity to install a particular extension. The push notification claims that installation of the add-on is the only way to leave this website. Usually, the message includes “Add Extension” and “Cancel” button. Apparently, both of them are designed to install the extension. The “Cancel” button aims to trick users and force them to install System Health Checker extension. Clicking it leads changes the notification into a dialog box that suggests ticking “Prevent this page from creating additional dialogs” option. If you decide to do that, your browser will be launched in full-screen mode, and you will be forced to install it. However, in order to avoid System Health Checker hijack, you should force quit the browser instead of clicking any buttons.

We also want to point out that redirects to these sites are triggered by an adware program that resides on the computer. It might have entered the system during incorrect installation of freeware or shareware. Thus, if you have recently installed a free program under Quick/Recommended settings, the System Health Checker adware might have been installed silently as well. Bear in mind that these settings do not openly disclose about additional third-party programs that are included in the software package. In order to avoid PUPs, you need to install new programs under Advanced/Custom settings.

Tips for System Health Checker removal

System Health Checker removal requires deleting browser extension and adware program that is responsible for redirects to suspicious sites. We highly recommend performing this task automatically. As we have mentioned, this add-on is quite hard to remove manually because it prevents users from accessing Chrome’s extensions list and has an invisible icon. Meanwhile, powerful anti-malware program can quickly locate and remove System Health Checker together with its components. However, if you insist of terminating this PUP manually, please follow our prepared instructions below.

How to prevent from getting adware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

 

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
