  1. Open the browser and select the menu icon.
  2. From the menu, click on the Add-ons button.
  3. Look for the Mystic Stealer extension
  4. Get rid of Mystic Stealer 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.

  • Find and uninstall any Edge extensions that look undesirable and unwanted.
  • Select Settings from the browser menu and click on Appearance.

How to Delete Mystic Stealer

  1. Open task manager
  2. Look for the Mystic Stealer process
  3. Select it and click on End task
  4. Open the file location to delete Mystic Stealer
  • 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 malicious 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

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.

    What is Mystic Stealer?

    There are two main reasons why the Trojan Horse viruses are so common and so widespread around the web. The first one is that they are very stealthy, and are able to avoid detection for long periods of time. This allows them to prolong the duration of their nefarious processes, making them more beneficial to their criminal creators. 
    The second reason is their versatility. Trojans like Mystic Stealer have the ability to perform a broad variety of criminal actions, making them invaluable to any hacker, who wants to harm your computer. Basically, they are multi-purpose instruments that can be programmed to accomplish almost anything you might think of.
    Perhaps, the most common use of such Trojans is theft of digital data. It could be theft of files, provided that you have some particular information that is of interest to the hackers. In most often, it’s just general theft of all kinds of personal data, such as passwords, login details, online banking details, credit, and debit card numbers, etc. There are various ways through which the hackers can get hold of such information, including methods such as keylogging, screen monitoring, or even hacking into one’s webcam, and mic, and obtaining remote access to the computer. The latter requires more resources and advanced coding, but some of the most successful strains of Trojan horse viruses have been known to secretly keep tabs on their victims’ activities, and transmit the collected information to the hackers’ remote servers.
    In other words, such malware can access all the data that you keep on the computer, and share it with people with malicious intentions.
    Another possible reason for nesting a Trojan like Mystic Stealer in your system is for the insertion of other viruses and malware. Damaging infections such as Ransomware or Rootkits can secretly sneak inside the compromised computer thanks to the vulnerabilities the Trojan Horse creates.
