Sepdot suddenly made a splash on the malware scene recently. This article helps with the removal of Sepdot from your PC in the most efficient manner. 


In case you missed the big news more than £20m were stolen from British bank accounts, leading many to question PC security measures against malware. Further reports state that over $10 million in the US were also lost to the Sepdot Malware Trojan since it first appeared on the scene. A later man-hunt conducted by joint USA (FBI) and UK authorities managed to apprehend some of the culprits, but not all of them. All of these problems could have been easily reverted if people whose computers where infected by this Trojan managed to remove it in time.

In an age where world economy is almost completely reliant on computers, it is evident that loopholes are way too many for any normal system to be flaw-free. You might have noticed me saying “any normal system.” What comprises a super high-level security system is a very vague subject, which is the entire reason for the emerging PC security sector. There are as many opinions as firms that provide such services out there, but one thing is for certain – every security is cracked at some point. Most often, however, it is not the security that falters, it is some action performed by the human user that invalidates the security protocols set up to protect him.

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

How to remove Sepdot

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

How to Delete Sepdot

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

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

    The Sepdot virus used use an especially elaborate scheme involving spam email attachments. These are fake emails that imitate real legitimate companies which send you invoices and attachment files supposedly by mistake.
    The basic scheme is to involve your curiosity by making you believe it’s the real deal. Once you open the invoice attachment to the email however, you are infected with the Sepdot Malware Trojan. Note that whatever tricks the hackers use to make you believe the email is legitimate the file inside will always end in .exe in order to be able execute the virus. Office files and other documents are never .exe files, only programs are. Trojans, unlike normal programs cannot be easily uninstalled.These “techniques” for infecting users are called “macros” and they prove a very valuable point. Most of these malware can not latch on to you unless you interact with them in some way. How, what and when is always different, but in the most basic level these things need YOU to get in. There have been numerous attempts to embrace a philosophy of prevention – when anti-virus programs annoyingly block your access to certain websites with the words these websites are unsafe. Browsers like Chrome, Firefox or IE have some in-built protection against such sites – the most dangerous ones are “blacklisted” and you’ll get a warning if you are redirected to such a site.

    Is Sepdot dangerous?

    Most users never fully realize what is really stake at this point. Once inside, the macro created by Sepdot Malware Trojan starts to simply record. Unlike a typical Adware it will not create any pop-ups, Ads or give any other indication of its presence – it will simply lurk hidden. It records your browsing habits, activities, and eventually when the time is right, it sends the information to whoever created it. The issue is that the information it provides is not limited to web browsing, but also to any passwords and personal credentials you input after the infection spreads. This means that prolonged exposure to the Trojan also maximizes the damage it inflicts. Removing Trojans like Sepdot and Wup.exe should be the top priority of any user.
