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

How to remove DotRunpeX

  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 DotRunpeX in the programs list that would show up.
  3. Select DotRunpeX 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 DotRunpeX.
  • If you find any of the programs suspicious then uninstall them if they turn out to be linked to DotRunpeX.
  • 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 DotRunpeX 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 DotRunpeX 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 DotRunpeX 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 DotRunpeX 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 DotRunpeX extension
  4. Get rid of DotRunpeX 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 “DotRunpeX” or another unwanted app, change it to an address that you’d want to be the browser’s new-tab page.

How to Delete DotRunpeX

  1. Open task manager
  2. Look for the DotRunpeX process
  3. Select it and click on End task
  4. Open the file location to delete DotRunpeX
  • 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 “DotRunpeX” 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 DotRunpeX

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

    What is DotRunpeX?

    However, usually damaging your computer or data isn’t the primary goal of the people behind threats like DotRunpeX and Trojan Win32/Casdet rfn. Instead, they might try to use the virus to spy on your activities or to take over your computer and then force it to carry out different tasks that would benefit the hackers. Some examples of such tasks are mining of cryptocurrencies, spreading spam messages, and participating in large-scale coordinated DDoS attacks. In all those cases, the user is likely to notice a severe slow-down of the computer as well as frequent crashes, freezes, software unresponsiveness, and other similar stability issues.
    As we already mentioned, a Trojan could spy on you and secretly collect personal data from your machine. This data could be used by the hackers to steal money from you, harass you, or to blackmail you. Another way a Trojan horse like DotRunpeX could be used for blackmailing you (this time indirectly) is when it inserts a Ransomware in your system that can encrypt your data, thereby keeping you from accessing it until you carry out a ransom payment.

    Is DotRunpeX dangerous?

    Faithful to it name, the DotRunpeX malware infection is usually disguised as something that users wouldn’t initially see as dangerous. One of the most effective ways to disguise the DotRunpeX malware is when the threat is made to look like an expensive program or game that is being distributed for free so that users would be tempted to download it.
    In most cases, such programs can be found uploaded to pirate sites and that is why hackers oftentimes use such sites to spread disguised Trojans. Two other common ways for spreading such threats are spam messages and misleading click bait adverts so be sure to avoid those as well so that you don’t land more Trojans in the future.
