How irritating is this problem? (5 votes, average: 5.00)

This page aims to help you remove Chairgaubsy. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

If your browser is getting swarmed by random ads, offers about different products, unexpected update prompts about software that you rarely have to update and if your browser is frequently getting redirects to sites with promotional and advertising contents or any site in general that you did not want to visit, then you most certainly have some form of a browser hijacker inside your PC. A hijacker is an app different from viruses and malware programs like Trojans, Rootkits, Ransomware and Spyware – it isn’t an inherently dangerous piece of software. However, it can mess with the way your browser functions and may even make changes to its starting page address, to its toolbar buttons and to its search engine. Usually, this could happen to any browser but the most common targets of browser hijackers are popular browsing programs – ones like Chrome, Edge, Firefox and Safari. One recently reported software piece named Chairgaubsy is what we are mainly going to be focusing on throughout the following lines as this app also seems to possess certain traits and features that lead us to categorize it as a browser hijacker. Chairgaubsy is likely to show intrusive advertisements inside the browser and redirect the users’ browsing to different pages that the hijacker tries to promote in attempts to increase their traffic. Also, as mentioned above, changes to a number of the browser’s settings are also likely to take place and overriding those changes may not be possible whilst the potentially unwanted app is still present and active inside the system. For that reason, we have prepared a set of instructions organized in an easy-to-understand and follow guide manual that will show you hot to uninstall Chairgaubsy. Additionally, we have added a tested removal tool to the guide for those of you who may require additional aid.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous.

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:

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.

Some more facts about the apps of the browser hijacker family

Even if you don’t really mind the ads or if you are getting some use out of the hijacker (as unlikely as both of those cases may be), you are still advise to remove the app from your browser and system because there may be certain security hazards which may arise due to the hijacker’s presence on your computer. Now, we are still not implying that Chairgaubsy is some sort of a virus or a malware program similar to a Trojan virus or a Ransomware cryptovirus. That being said, though, due to the uncontrolled nature of the types of ads that get shown on your screen and due to the likelihood of getting redirected to some less-than-reliable web address as a result of the hijacker’s activity, it is simple better to not allow this piece of software to remain on your computer for any more time than it already has. As we said, the instructions from this page as well as the recommended removal program should be more than enough to enable you to eliminate Chairgaubsy and so we urge you to give them a try and clean your computer.
