The Check Robotics Virus

In case you’re on this website, you have probably been heavily disturbed by the constant flow of aggressive advertisements, which the Check Robotics virus has started to display on your Chrome, Firefox, Edge, or any other web browser. You may also have found that some unexpected “improvements” have happened in your default browsing application caused by the Check Robotics virus.

For example, a new search engine or a different homepage has been introduced along with some new tab page changes or some strange redirect buttons. These are the typical symptoms of having a browser hijacker on your system and if your attempts to remove those changes have been unsuccessful so far, the paragraphs that follow can be of great use. There you will find more information about the specifics of Check Robotics, a detailed manual removal guide and a professional removal tool that can help you uninstall the unwanted program.

What stands behind the term “browser hijacker”?

The word browser hijacker is a common word used for programs that have been designed to show a broad range of advertisements on your computer’s screen. Most browser hijacker applications can also redirect the search requests of their users to other websites and sponsored links. This is usually done with the idea to generate traffic and clicks on specific pages that pay for promotion and visibility. One explanation that such browser hijacker programs may frequently be considered questionable is because they may often redirect you to low-quality pages or links that might be compromised by malware such as Ransomware or viruses. Nevertheless, this is not the main purpose of programs such as Check Robotics.

The Check Robots Virus

In reality, apps like Check Robots, iStart Search Bar, are simply online advertising tools that only search for the most effective ways in which certain goods, services, and their related websites can be marketed on your screen. Apps like the Check Robots virus are generally not harmful and do not normally damage the machine in any way. However, they are not protected by malware code that can sneak inside the stream of regularly displayed web ads and links.

That’s why you should always proceed with caution if you are about to click on the promotional messages and redirect prompts that you see on your monitor. Some of them may be infected by real viruses and once click will be enough to catch threats such as Ransomware, or Trojan horse viruses. Of course, this is not the rule and may never happen but it is still a possibility which can be a good enough reason for some people to uninstall pieces like Check Robotics without regret.

But even if that is not the case, because of their disruptive and aggressive behavior and the modifications they usually make to the default browsers without requesting permission, a number of web users consider browser hijackers to be potentially unwanted pieces of software.

The good news is that, when removed, these programs can no longer mess with the settings of the web browser and cannot spam it with nagging pop-ups, pop-unders, banners, text messages, etc. Your attempts to open a new page or start a new browsing session will also no longer be interrupted by automatic redirects to pages that are unfamiliar to you. That’s why, if you want to regain control over your web surfing activity right away, we encourage you to use the steps in the removal guide below or perform a system scan with the professional Check Robotics removal tool that is attached to the guide.

    After you open their folder, end the processes that are infected, then delete their folders. 

    Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


    Hold together the Start Key and R. Type appwiz.cpl –> OK.


    You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

    Type msconfig in the search field and hit enter. A window will pop-up:


    Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


    Hold the Start Key and R –  copy + paste the following and click OK:

    notepad %windir%/system32/Drivers/etc/hosts

    A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

    hosts_opt (1)

    If there are suspicious IPs below “Localhost” – write to us in the comments.

    Open the start menu and search for Network Connections (On Windows 10 you just write it after clicking the Windows button), press enter.

    1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.
    2. The DNS line should be set to Obtain DNS server automatically. If it is not, set it yourself.
    3. Click on Advanced —> the DNS tab. Remove everything here (if there is something) —> OK.



    • After you complete this step, the threat will be gone from your browsers. Finish the next step as well or it may reappear on a system reboot.

    Right click on the browser’s shortcut —> Properties.

    NOTE: We are showing Google Chrome, but you can do this for Firefox and IE (or Edge).
