Chrome_Help is an undesirable app capable of hijacking important browser elements such as the search engine or the toolbar and injecting them with ads. The goal of apps like Chrome_Help is to generate revenue through ads and page-redirects that they generate inside the users’ browsers.

The Chrome_Help virus will try to mess with your browser settings

It can often be a frustrating and maybe even anxiety-inducing experience to get browser-hijacking apps like Chrome_Help, Go go Tech or Main Captcha Top attached to a browser. For starters, the presence of such software in the computer can significantly affect the way browsers like Chrome, Firefox, Safari, or Edge operate. All of a sudden, the starting page of the browser may get replaced, you may start seeing obstructive and obscure ads showing up on your screen and certain questionable sites may start to automatically open in the browser. All of this could easily make anyone think that their system has been infected by a dangerous piece of malware from the Trojan Horse category or a file-encrypting Ransomware virus that can, in a matter of minutes, lock up all user data present on the computer. Fortunately, none of those things apply to a browser-hijacking app like Chrome_Help. Instead, this is a simplistic advertising tool that doesn’t have any overly-advanced functions and cannot harm your computer in a direct way. However, its important to still note that apps like this are not considered safe and it’s best to avoid them as much as possible. In case you already have Chrome_Help inside your browser, the best advice we could give you with regard to it is to uninstall the intrusive app. Not only would that end its constant generation of obnoxious advertising content but it will also help you significantly improve the safety of your computer.

Why and how could a hijacker app be hazardous?

Despite the overall harmlessness of the applications of this category, users need to keep in mind that, under certain circumstances, the activities of a browser hijacker inside the browser could potentially result in attacks from much more dangerous and unpleasant forms of malware. We already mentioned some such malware forms – the Trojan Horse and the Ransomware category – however, there are many other dangerous threats out there that could also target your PC if a hijacker is allowed to operate on it for long periods of time.

The thing that may compromise your system is the ads and redirects spammed by Chrome_Help. Even though most of them would probably be legitimate, it is not impossible for harmful and misleading ads to find their way into the advertising stream of the hijacker and to end up on your screen. Clicking on such an ad could, obviously, get you redirected to a harmful site that can then automatically download malware on your computer. The biggest issue here is that it is often difficult to tell apart legitimate and misleading online ads. Besides, in some cases, Chrome_Help may get you to click on a given ad without you necessarily wanting to do it. For example, right before you click on a certain link, the ad may appear in front of your cursor so you’d end up clicking on it instead of the link. This is why the best way to protect your computer is to remove the hijacker altogether and uninstall any changes it may have made inside the browser.

    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).


    Properties —–> Shortcut. In Target, remove everything after .exe.
