123w0w.com is a type of browser-infecting malware that initially appears similarly to a browser extension but soon after installation hijacks the search engine and the homepage. 123w0w.com is created for the purposes of web-advertising and will spam you with different ads and site-redirects.


A particular kind of software apps is in most cases the cause behind any excessive or nagging browser adverts, especially if the latter aren’t attached to a certain webpage. 123w0w.com is one such invasive and ad-generating piece of software. What you’re dealing with is known as browser hijacker software and it’s been the cause for many users’ aggravation for quite some time now. A lot of browser hijacker programs get installed together with other useful programs but this isn’t always the case. Any software that carries obstructive amounts of advertisements integrated in it could be labelled as a browser hijacker. One certain way to tell if an application is a browser hijacker is to decide whether the benefits it gives are worth putting up with the adverts it creates. Browser hijacker programs are undoubtedly what you might regard as unwanted in this situation. The best course of action when we’re talking about browser hijackers is to remove it from your PC as soon as possible and our guide will help with that.

The 123w0w virus

An especially frequent misunderstanding is to mistake the 123w0w virus for a computer virus since the latter happens to be a frequently used word for all that could possibly go wrong with a computer. To make the difference between the 123w0w virus and viruses, remember that the representatives of the latter category are ultimately lawful and mostly harmless while the computer viruses are used in cyber crimes, for example data robbery and espionage.

How to remove 123w0w.com

  1. First, click the Start Menu on your Windows PC.

  3. Select 123w0w.com from the list and click on Uninstall.
  4. Follow the steps in the removal wizard.

What we suggest you do first is, check the list of programs that are presently installed on the infected device and uninstall any rogue software that you find there:

  • From the Start Menu, navigate to Control Panel ->>> Programs and Features ->>> Uninstall a Program.
  • Next, carefully search for unfamiliar programs or programs that have been installed recently and could be related to 123w0w.com.
  • If you find any of the programs suspicious then uninstall them if they turn out to be linked to 123w0w.com.
  • If a notification appears on your screen when you try to uninstall a specific questionable program prompting you to just alter it or repair it, make sure you choose NO and complete the steps from the removal wizard.

Remove 123w0w.com from Chrome

  1. Click on the three dots in the right upper corner
  2. Go to more tools
  3. Now select extensions

  • Once you open Chrome, click on the three-dots icon to open the browser’s menu, go to More Tools/ More Options, and then to Extensions.
  • Again, find the items on that page that could be linked to 123w0w.com and/or that might be causing problems in the browser and delete them.

  • Note that the App Data folder is normally hidden so you’d have to first make the hidden files and folders on your PC visible before you can access it.

How to get rid of 123w0w.com on FF/Edge/etc.

  1. Open the browser and select the menu icon.
  2. From the menu, click on the Add-ons button.
  3. Look for the 123w0w.com extension
  4. Get rid of 123w0w.com by removing it from extensions

If using Firefox:

  • Open Firefox
  • Select the three parallel lines menu and go to Add-ons.
  • Find the unwanted add-on and delete it from the browser – if there is more than one unwanted extension, remove all of them.
  • Go to the browser menu again, select Options, and then click on Home from the sidebar to the left.
  • Check the current addresses for the browser’s homepage and new-tab page and change them if they are currently set to address(es) you don’t know or trust.

If using MS Edge/IE:

  • Start Edge
  • Select the browser menu and go to Extensions.
  • Find and uninstall any Edge extensions that look undesirable and unwanted.
  • Select Settings from the browser menu and click on Appearance.
  • Check the new-tab page address of the browser and if it has been modified by “123w0w.com” or another unwanted app, change it to an address that you’d want to be the browser’s new-tab page.

How to Delete 123w0w.com

  1. Open task manager
  2. Look for the 123w0w.com process
  3. Select it and click on End task
  4. Open the file location to delete 123w0w.com
  • Access the Task Manager by pressing together the Ctrl + Alt + Del keys and then selecting Task Manager.
  • Open Processes and there try to find a process with the name of the unwanted software. If you find it, select it with the right button of the mouse and click on the Open File Location option.
  • If you don’t see a “123w0w.com” process in the Task Manager, look for another suspicious process with an unusual name. It is likely that the unwanted process would be using lots of RAM and CPU so pay attention to the number of resources each process is using.
  • Tip: If you think you have singled out the unwanted process but are not sure, it’s always a good idea to search for information about it on the Internet – this should give you a general idea if the process is a legitimate one from a regular program or from your OS or if it is indeed likely linked to the adware.
  • If you find another suspicious process, open its File Location too.
  • Once in the File Location folder for the suspicious process, start testing all of the files that are stored there by dragging them to our free online scanner available below.
  • Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
    This scanner is free and will always remain free for our website's users.

    • If the scanner finds malware in any of the files, return to the Processes tab in the Task Manager, select the suspected process, and then select the End Process option to quit it.
    • Go back to the folder where the files of that process are located and delete all of the files that you are allowed to delete. If all files get deleted normally, exit the folder and delete that folder too. If one or more of the files showed an error message when you tried to delete them, leave them for now and return to try to delete them again once you’ve completed the rest of the guide.

    How to Uninstall 123w0w.com

    1. Click on the home button
    2. Search for Startup Apps
    3. Look for 123w0w.com in there
    4. Uninstall 123w0w.com from Startup Apps by turning it off
    • Now you need to carefully search for and uninstall any 123w0w.com-related entries from the Registry. The easiest way to do this is to open the Registry Editor app (type Regedit in the windows search field and press Enter) and then open a Find dialog (CTRL+F key combination) where you have to type the name of the threat. 
    • Perform a search by clicking on the Find Next button and delete any detected results. Do this as many times as needed until no more results are found. 
    • After that, to ensure that there are no remaining entries lined to 123w0w.com in the Registry, go manually to the following directories and delete them:
    • HKEY_CURRENT_USER/Software/Random Directory. 
    • HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Run/Random
    • HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Main/Random

    Is 123w0w.com a virus?

    Currently, by far the most harmful and often encountered malicious program family is known as Ransomware. Ransomware will definitely cause all the target’s private files to become unusable until a ransom is handed over. Anyone worried that 123w0w.com may be a scary virus can relax now – the browser hijackers can usually be eradicated without major negative effects. We do not, however, say that you should keep nagging browser hijackers similar to 123w0w.com installed on your system – exactly the opposite. Yet, it’s essential to take care of this threat while remaining relatively calm. The unfortunate truth is that many browser hijacker pieces are technically legal by the law and thus many anti-virus software programs will take no action against them.

    Is 123w0w.com dangerous?

    Don’t be surprised when the advertisements you see on your monitor are overly-intrusive and aggressive – this is to be expected for almost all browser hijacker programs. It’s likely that you’d be unable to use your internet browser due to the constant barrage of pop-ups, box-messages and banners. A lot of people arrive at the conclusion that their machine has been infected by some sort of a dangerous virus after experiencing all those ads. As frustrating as the browser hijacker is, however, it is really not a malicious virus. You can tell if a program is malicious by looking at its behaviour and how it interacts with the data in the system. The goal behind most browser hijackers would be to generate as many ads as possible and also to make themselves hard to eradicate. Commonly, the browser hijackers function through installing some add-on element to your web browser that may be invisible and/or tricky to remove. You probably wonder why these programs are created to begin with. You see, the online advertising industry is really big and profitable right now. Generally, software applications such as 123w0w.com and Captcha Glow make use of the so-called pay-per-click method, which gains revenue for the browser hijacker creator for each click any of the advertisements receive.
