Bengekoo Virus


Bengekoo is what experts classify as your typical browser hijacking program. It is called that way, because once Bengekoo gets into your system, it will ‘hijack’ the settings of your main browser.


The Bengekoo Virus will redirect your browser when you try to use it.

And with that said, we should also point out that browser hijackers like this can infiltrate pretty much any browsing program out there. This includes but is not limited to Chrome, Firefox and Edge. Now as for the settings that a program like Bengekoo can hijack, usually these have to do with the browser homepage and its default search engine, as well. You may have already discovered that these particular elements in your browser have been changed.

In addition, browser hijackers like this tend to add extra elements to the browser such as add-ons and new toolbars. But what’s most characteristic of these types of programs is that they install ad-generating components in the infected browser. And as a result, your browser becomes flooded with popups, in-text links, box messages and banners in every shape and size. And let’s also not forget to mention the highly annoying page redirects that software of this type triggers.

All of this is done with the intention of promoting certain products and services. On in the case with the homepage changes, for instance, it’s to drive more traffic to a certain website. But it all essentially boils down to generating profit for the browser hijacker developers.

Software like Bengekoo is often engaged in popular online business models such as Pay Per Click and Pay Per View. Hence, every time a user clicks on some of the displayed ads, the developers earn some small commission. This should explain the rather aggressive placement of the ads on your screen. But if you’d like to rid yourself of all these unnecessary changes, you can do so only by removing Bengekoo from your computer. This can be done by following a series of steps which we’ve described in the removal guide below.

The Bengekoo Virus

Browser hijackers like the Bengekoo virus aren’t generally considered to be harmful, but experts still put them in the category of potentially unwanted programs or PUPs. What this means is that although the Bengekoo virus may not do anything to cause direct harm on your PC, it is still undesirable for a number of reasons.

For one, their presence could potentially result in exposure to viruses and malware. For example, if you are redirected to a website that is insecure or has been tampered with by hackers, you could face threats like Trojan horse viruses, rootkits, ransomware and others.

In addition, due to the way that browser hijackers generate profit for their developers, they may engage in certain activities to boots these profits. Namely, software with Bengekoo is often associated with various data-collection techniques from users’ browsers. They can look into your browsing history, determine your patterns and define the type of content you tend to gravitate towards. And this information can be used to showcase tailored ads for your specifically. However, on the downside, this information may also be distributed to third parties, which is hardly something any user would be too happy about.

    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.
