The Sossiotron is a rogue webpage that steals the settings of your browser by installing a rogue browser hijacker in it. The Sossiotron hijacker can get attached to any browser – Chrome, Firefox, Opera, etc. – and flood it with aggressive pop-up ads and page-redirects.

As soon as this browser hijacking-software gets added to your browser, you will know that it is there. Changes to the starting page of the browser, to its default search engine, as well as frequent page-redirects to unknown and questionable pages are all sings that there’s something undesirable added to the browser you are using at the moment. However, note that there are a lot of sketchy sites with overly-aggressive ads that cause the browser to behave in a similar way. If the ads, pop-ups, and page-redirects cease once you leave such a site, then the issue was probably with that site alone and not with your browser. However, if the obstructions persist no matter what site you are on, then you most certainly have some sort of hijacker like Sossiotron in your browser that must be dealt with.

Please follow all the steps below in order to remove Sossiotron!

How to remove Sossiotron

  1. First, click the Start Menu on your Windows PC.
  2. Type Programs and Settings in the Start Menu, click the first item, and find Sossiotron in the programs list that would show up.
  3. Select Sossiotron 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 Sossiotron.
  • If you find any of the programs suspicious then uninstall them if they turn out to be linked to Sossiotron.
  • 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 Sossiotron from Chrome

  1. Click on the three dots in the right upper corner
  2. Go to more tools
  3. Now select extensions
  4. Remove the Sossiotron extension
  • 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 Sossiotron and/or that might be causing problems in the browser and delete them.
  • Afterwards, go to this folder: Computer > C: > Users > *Your User Account* > App Data > Local > Google > Chrome > User Data. In there, you will find a folder named Default – you should change its name to Backup Default and restart the PC.
  • 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 Sossiotron 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 Sossiotron extension
  4. Get rid of Sossiotron 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 “Sossiotron” or another unwanted app, change it to an address that you’d want to be the browser’s new-tab page.

How to Delete Sossiotron

  1. Open task manager
  2. Look for the Sossiotron process
  3. Select it and click on End task
  4. Open the file location to delete Sossiotron
  • 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 “Sossiotron” 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.
    This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    • 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 Sossiotron

    1. Click on the home button
    2. Search for Startup Apps
    3. Look for Sossiotron in there
    4. Uninstall Sossiotron from Startup Apps by turning it off
    • Now you need to carefully search for and uninstall any Sossiotron-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 Sossiotron 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

    How dangerous is Sossiotron?

    Though unwanted software components like the Sossiotron browser hijacker and Captcha Fair are commonly referred to as viruses, they aren’t actually very dangerous by themselves. For the most part, they are more of an irritating obstruction rather than an actual threat to the user’s online security and privacy. That said, you shouldn’t underestimate a browser hijacker because, even though it’s probably not capable of directly harming your system, there’s always a chance that the content it spams you with may be unsafe. For example, many online scammers use browser hijackers to lure potential victims to their phishing or malware-distributing sites, where the user may have their personal data stolen or from where they may unknowingly download a malicious program such as a Trojan or a Ransomware onto their computer.
    All in all, even if Sossiotron is not as dangerous as some users may fear, it could easily end up being a gateway for significantly more problematic threats, which is the reason its removal is highly advisable.

    How to deal with Sossiotron?

     Dealing with browser hijackers isn’t overly complicated, and you should be able to delete this one from your computer with the help of the guide shown below and/or with the help of the professional anti-malware tool posted on this page. However, it’s not enough to simply delete this rogue app – you must also make sure to keep other such unwanted programs away from your PC in the future. To prevent other hijackers from getting installed in your system and browsers, you need to avoid visiting sketchy sites and downloading questionable free software. Also, if you get a suspicious pop-up in your browser when you try to visit a certain website, do not interact with it and instead simply close that browser tab/window. A lot of hijacker sites take over the user’s browser via disguised site-permission pop-ups that users often click on without stopping to think what about what they are actually interacting with. Last but not least, if you are installing a new program on your PC, check the Advanced/Custom settings in the installation manager and uncheck any optional bonus/additional components that you don’t need to get installed on your computer. Oftentimes, such optional installs are browser hijackers, adware, or another form of potentially unwanted programs, so they are usually best left out of the installation process.
