Marspeedp is an unwanted browser extension that experts label as a browser hijacker. Marspeedp infects browsers like Chrome, Edge, and Firefox, and makes changes in them that might jeopardize your computers security.

The Marspeedp Virus

If the ads in your browser have started to show up more frequently than normal, and if some strange changes have taken place in the browser, then you might have what is known as a browser hijacker in your system. A Browser hijacker is an app that could set a new homepage address to your browser, as well as replace some other elements in the program like its toolbar buttons and its default search engine service. Additionally, most hijackers are famous for page-redirecting the browser to certain sites that are supposed to get their traffic increased in this way.

Of course, having such an app in your Chrome, Edge, Safari, or Firefox browser is definitely not something you would like since all of these changes and page redirects could severely obstruct your online activities and make using your browser rather difficult and frustrating. The good news is that this isn’t a threat that can directly harm your computer or cause any long-lasting consequences. The hijacker apps are less problematic than ransomware, worms, viruses, Trojans, and other high-danger threats, and that is why you shouldn’t panic if you see one in your computer. What you should still do, however, is remove the invasive app from your system, as it may still cause certain issues if it stays in the computer for long, and if you are not careful with its ads, page redirects, and banner pop-ups.

A hijacker such as the new Marspeedp can expose your system and privacy to certain risks. This isn’t the goal of this program, and it still doesn’t mean that you are dealing with a Trojan or a ransomware virus, but the fact that there is an app in your system that can randomly redirect you to all kinds of sites and show ads on your screen that have unknown origins is bound to increase the chances of landing malware or getting sent to some phishing page. Many Internet scammers and hackers are known for using methods such as malvertising to lure their victims and trick them into downloading some harmful malware, or providing their banking details, thinking they are interacting with a legitimate page. There are all kinds of such dangers on the Internet, and what basically happens when there is a hijacker in your system is that the chance of getting exposed to such dangers would be greatly increased.

Luckily, there’s an easy way out – our guide below has all the info you might need in order to get this hijacker uninstalled in a quick and reliable way. Just remember to do everything as instructed and if you aren’t sure about something ask us about it in the comments.

One thing you must not forget is to keep your computer clean in the future. To do that, make sure to never download programs from unknown and potentially unsafe sources. Also, always check each program installer for added components that you might not need by opening its custom setup menu. There, if you see some sketchy bonus app, uncheck it as it might be some form of junkware such as a browser hijacker.

Marspeedp Virus Removal

The following directions may help you remove Marspeedp from your browser’s extensions list:

  1. Tap on your browser’s Settings option and select More Tools/Add-ons,
  2. Choose the Extensions tab and search for Marspeedp in the list of installed extensions.
  3. When you spot Marspeedp, highlight it and click on the Trash Bin icon to remove it.
  4. Scroll the Extensions list once again for other potentially unwanted extensions and add-ons and remove them in the same manner.

If these directions cannot help you solve the browsing issue caused by Marspeedp, please follow the comprehensive Marspeedp removal guide published below: 


Bookmark this page as you may need it for reference later in the steps and restart your device in Safe Mode.


Once you successfully boot in Safe Mode, open the Task Manager (CTRL + SHIFT + ESC) and go to the Processes Tab.

If you are using Windows 8 or 10, the Processes tab there is called “Details“, so make sure you select it.

Next, check for Marspeedp processes in the list and if you see any, right-click on it and pick Open File Location.


The next thing to do is to scan the files in that location with the free online virus 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.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    If the scanner shows that the files are dangerous, end the related processes by right-clicking on it and choosing the End Process Tree option. Also, don’t forget to delete the flagged files and their folders from the File Location.

    Please note that you can scan the files of any process that looks suspicious. However, make sure that you research every process online as the deletion of legitimate system processes may cause great damage to the OS.


    In the second step of this guide, type System Configuration in the Windows search field and open it. Click on the Startup tab and, under Startup Items search for Marspeedp. It is common for Browser Hijackers like this one to add themselves to the Startup so they can launch upon system startup. If you find Marspeedp in the list, highlight it and remove its checkmark.


    If you find entries that have “Unknown” Manufacturer or are unfamiliar to you and look questionable, it is best to research them online and only then decide whether to uncheck their checkmark or not.  When you finish, click OK to save the changes.

    Note! Pay attention that unchecking system-related entries from the Startup may affect the smooth operation of your system and some essential startup processes.

    Next, open a Run window by pressing the Start and R keyboard keys simultaneously. After that,  type appwiz.cpl in the text field and click OK:


    You will find yourself inside the Control Panel where you can review all apps that are installed on your computer. Once in there, search for Marspeedp and uninstall it as soon as you detect it


    Some of the Marspeedp-related entries may have been added to the Registry. That’s why in the next instructions we will show you how to find and delete them:

    • Type Regedit in the search field and press Enter
    • Once in the Registry Editor press CTRL and F keys together to open a Find window.
    • In the Find window, type the name of the browser hijacker in question.
    • Click on the Find Next button.
    • Delete the results by right-clicking on them.

    Next, go to all of the following directories and manually delete/uninstall 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

    Feel free to ask us in the comments if you can’t decide which directory should be removed.

    After all Marspeedp traces are deleted from the Registry, click on the Windows Start button and search for Network Connections.  Open it and carefully repeat the instructions below:

    1. Tap on the currently used Network Adapter and right-click it.
    2. Click on Properties and select Internet Protocol Version 4 (ICP/IP).
    3. The Properties button below will become active. Click it.
    4. Select Obtain DNS server automatically and click on Advanced.
    5. Open the DNS tab and remove everything that has been added in the DNS server addresses section.
    6. Confirm your changes by clicking the OK button.


    The following directions will hopefully help you find and remove Marspeedp from your hijacked browsers. 

    Note! The directions that you will see explain the steps in Google Chrome, as this is a commonly used web browser. However, the same directions could successfully be applied to other browsers as well, so don’t hesitate to use them in your case.

    Highlight the shortcut icon of the hijacked browser, then right-click it and select Properties.

    Once the Properties window appears, click on the Shortcut tab and go to Target.

    Browser Hijacker Removal Instructions

    After you are done with that, close Google Chrome and manually navigate to User Data by following this path: 

     C:/Users/!!!!USER NAME!!!!/AppData/Local/Google/Chrome/User Data. 

    Once in User Data, search for a folder called “Default” and when you find it, change its name to Backup Default. Do a browser restart after that.

    Rename the Folder to Backup Default

    To rule out any possibilities for confusion, below we will show you how to find and remove Marspeedp from two more popular web browsers. Here are the basic directions:

    ie9-10_512x512  Remove Marspeedp from Internet Explorer:

    When you open Internet Explorer go directly to the upper right corner and click  IE GEAR. After that, select Manage Add-ons:

    pic 3

    If Marspeedp has installed an add-on inside the browser, find it and select Disable. 

    After that, go back to the gear icon  IE GEAR and click it. Select Internet Options this time.

    In case that Marspeedp has placed its own homepage URL in the homepage field, change it to a URL that you trust and want and click on Apply.

    firefox-512 Remove Marspeedp from Firefox:

    The directions in Firefox are almost identical. But have a little twist. Once you open the browser go to the top right corner and click  mozilla menu .

    Select Add-ons and, after that, select Extensions from the left menu. Check if Marspeedp has installed itself as an Extension in the browser and if it is, highlight that extension and click on Remove.

    Finally, before you close this guide, it is a good idea to check your computer for signs of hacking. This could be done if you open your Hosts file. For that, press together the Start and R keyboard keys  and copy the following command in the Run window that appears on the screen:

    notepad %windir%/system32/Drivers/etc/hosts

    Hit the Enter key and scroll the Hosts file till you find Localhost.  

    hosts_opt (1)

    If you see any suspicious IPs below Localhost that look like the Virus Creator IPs in the illustrative image above, please leave us a comment below this guide.

    If after you try everything in this guide Marspeedp still doesn’t want to get removed completely, it is best to download the professional removal tool recommended on this page or another trusted security software of your choice, scan your computer with it and follow its instructions.
