Is Duelbits safe?

Duelbits isn’t as dangerous as those nasty malware or viruses that destroy your system and files. However, it is still a source of disturbance for many and may cause some serious trouble. Once installed, the program likes to play around with your browser settings without requesting an approval. And that’s not all! It specializes in redirecting your searches, bombarding your screen with pesky ads, and silently stalking your online activities. Such activities, though not directly harmful, can seriously mess with your privacy, expose you to dodgy websites, and make your browsing feel like a never-ending nightmare. That’s why it’s advisable to remove Duelbits from your system pand ensure a safe and enjoyable browsing journey.

Duelbits Virus

Many users who face Duelbits for the first time and experience some of its activities refer to it as the “Duelbits virus” initially. But, to your relief, this software is not a virus at all. In fact, unlike those nasty viruses that can wreak havoc on your system, (think of Trojan Horses or Ransomware), the “Duelbits virus” (or rather, Browser Hijacker) is more of an irritating program than a truly harmful piece of code. It won’t go around corrupting your files or infecting other computers. However, let’s not underestimate its annoying behavior. The hijacker can disrupt your browsing experience and, here’s the thing, it can also open doors for more serious threats to enter. So, it’s advisable to remove it from your system as a preventive measure.

What is Duelbits?

Browser Hijackers like Duelbits often tag along with free software downloads. If you’re paying close attention to the installation setting, you may find them in the fine print of a software agreement, hiding in plain sight. These pieces of software have one mission in mind: taking over your web browser. They’ll mess with your search engine, tweak your home page, and redirect your web searches to specific sites. And why? It is all about generating revenue from paid clicks on sponsored ads and sites! Programs like Duelbits , Advmonie or Fadszone want to rack up those advertising dollars, and they’re not shy about it. So, once such software sets up camp on your system, you can expect a stream of pushy notifications, practically asking you to click on them.

Duelbits Pop-ups

Duelbits is notorious for bombarding you with a never-ending stream of pop-up ads while you’re casually browsing the web. Sure, for some users, this is nothing more than a minor annoyance. But here’s the thing: the internet can be a dark and treacherous place, filled with sketchy ads, deceiving links, and websites just waiting to infect your device with all sorts of malware. So, when those random Duelbits pop-ups and notifications start vying for your attention, hold up! Not everything that glitters on your screen is gold. Some of those Duelbits pop-ups might try to trick you into downloading even more unwelcome software or expose you to malicious content. So, it’s better to err on the side of caution and avoid clicking on them.

Duelbits on Chrome

If you have Duelbits on Chrome, you may be greeted by a strange homepage, you may frequently see search results that are not related to your actual searches, or you may see suspicious toolbars making an unwelcome appearance in your taskbar. This is because, the hijacker has messed with Chrome’s settings, and has started redirecting you towards its preferred sites and ads. Sadly, Duelbits on Chrome won’t just get removed in the usual way that you use to remove browser add-ons, and your ad-blocker won’t stand a chance against its intrusive tactics – those aggressive pop-ups, ads, and redirects. So, to deal with it, you will need a detailed removal guide and a trusted security software, like those that you will find below.

The Duelbits app

The most notable symptom of browser hijacking are the Duelbits app redirects that keep happening at the most inconvenient moments. These forced visits to the Duelbits app can be highly frustrating for users affected by the hijacker. What’s more, every time you unwittingly fall into the redirect trap, you inadvertently contribute to the website’s increased ad impressions and click rates. The only effective way to stop this activity and regain control of your browser is to remove the hijacker that is causing it. But fret not, if you haven’t done this before because we’re here to help! Our comprehensive guide will explain to you everything you need to know to remove the unwanted software from your system and bid farewell to those irritating redirects once and for all.

Step1 Uninstall the Duelbits app and kill its processes

The first thing you must try to do is look for any sketchy installs on your computer and uninstall anything you think may come from Duelbits. After that, you’ll also need to get rid of any processes that may be related to the unwanted app by searching for them in the Task Manager.

Note that sometimes an app, especially a rogue one, may ask you to install something else or keep some of its data (such as settings files) on your PC – never agree to that when trying to delete a potentially rogue software. You need to make sure that everything is removed from your PC to get rid of the malware. Also, if you aren’t allowed to go through with the uninstallation, proceed with the guide, and try again after you’ve completed everything else.

  • Uninstalling the rogue app
  • Killing any rogue processes

Type Apps & Features in the Start Menu, open the first result, sort the list of apps by date, and look for suspicious recently installed entries.

Click on anything you think could be linked to Duelbits, then select uninstall, and follow the prompts to delete the app.

    Step2 Undo Duelbits changes made to different system settings

    • Task
    • Services

    Type in Start Menu: C:\Windows\System32\drivers\etc\hosts

    Delete Duelbits IPs from Hosts

    Type in the Start Menu: Startup apps

    Disable Duelbits startup apps

    Delete Duelbits scheduled tasks
