Checkrobotics is a browser hijacker app that can install in popular browsers like Google Chrome and Mozilla Firefox and change their settings without the user’s approval. Checkrobotics is deemed unwanted software because it spams the browser with ads and triggers sudden page redirects.
All Internet users are familiar with the annoyance brought on by the various forms of online advertisements we get exposed to each day. Checkrobotics is simply a tool for generating Pay-Per-Click ads through which its creators are able to earn money. Checkrobotics needs to hijack the browser’s settings in order to flood the browser with its ads, which is why it’s categorized as a browser hijacker. The use of Pay-Per-Click ads (ads that make money based on how many clicks they get from users) is a common practice nowadays and there are even legitimate sites and apps that employ it to generate extra income for their developers. However, if the ads are too much and/or too aggressive and obtrusive, the app showing it is regarded as potentially unwanted. Checkrobotics is a potentially unwanted app because the ads it shows in the user’s browser are known to make surfing the Internet rather difficult and frustrating. Also, Checkrobotics has been reported to automatically redirect users to sites with more aggressive ads. Considering all this, it’s easy to see why someone may not want to have this app in their browser. Checkrobotics is a software mainly focused on displaying ads in order to profit its creators without really offering the user anything useful. Checkrobotics is, therefore, both unneeded and unwanted in the computers it’s installed and people normally want to remove it. If that is why you are here too, know that we can lend you a hand with this hijacker’s uninstallation.
The Checkrobotics virus
If intrusive pop-up ads are preventing you from browsing the web normally, you may have the Checkrobotics virus in your browser. The Checkrobotics virus is an app that takes over the affected browser and begins to spam it with ads, page-redirects, and banners.
In addition, most browser hijackers modify some aspects of the browser and maybe even make changes in the OS in order to allow themselves to advertise on your screen without getting interrupted. Checkrobotics, for instance, might try to replace the search engine of the browser in order to alter the search results you get in favor of some advertised sites instead of showing you the most relevant entries. The homepage of the browser will also probably get change in order to boost the traffic to the site that’s now your new homepage. Chrome, Safari, and Firefox are some of the browsers that get commonly affected by hijackers.
Normally, most popular browsers such as the ones mentioned above have some form of anti-hijacker and anti-adware protection but the creators of apps like Checkrobotics have their ways of tricking the users into giving their Admin permission for the hijacker’s installation. In many instances, such apps are placed inside file-bundles – software installers that come with extra components include in them. The user normally only wants to install the main program from the installer, but if they forget to uncheck the optional bonus elements they’d get them installed as well. The browser hijackers are often distributed as such bonus elements and if you don’t’ pay enough attention to the installation wizards of programs you are about to install, it is highly likely to land a hijacker in the future. File-bundling, however, is only one of the many methods used to spread apps like Checkrobotics and Humisnee. Spam messages, misleading adverts, fake update requests (and sometimes even legitimate update requests) can all be used for hijacker distribution. Even if you are extremely careful and vigilant, you may still land a hijacker like Checkrobotics without knowing how it has happened. The good news is that it isn’t too difficult to remove such an app if you know what you are doing or if you have access to a reliable removal guide or anti-malware tool. Both of those are available right below this article and we advise you to scroll down to them once you finish reading here if you need to learn how to remove Checkrobotics.
Even though this app is far less problematic than a Ransomware virus or a Trojan Horse, we still encourage you to uninstall it because some of its ads could be unsafe and may lead you to sites that have threats like the aforementioned Trojans and Ransomware on their pages.
|Danger Level||Medium (nowhere near threats like Ransomware, but still a security risk)|
|Symptoms||Hijackers change the search engine of the browser and redirect the user to sites with many ads in them.|
|Distribution Method||Bundling the hijacker with other programs is the typical methods used to spread these apps.|
