Resmon

Resmon is a stealthy Trojan horse infection aimed at exploiting system vulnerabilities and launching harmful activities in the background of the system. Users infected with Resmon may experience system corruption, theft of personal data, espionage and many other criminal activities.

The Resmon virus. What is that process?

Resmon is a new Trojan horse representative that is currently distributed on the Internet with the help of many malicious transmitters. It is very likely to land this virus on your computer if you are not careful where you click online. Emails with malicious attachments, spam messages, malvertisements, and harmful pop-up links, could often be used to secretly spread Resmon all over the web. Low-quality web sites, cracked apps, torrents, and illegal platforms can also be places where such a Trojan infection can lurk and wait for its victims. The actual contamination usually involves interaction from the user’s side, such as actually clicking on an infected link, opening a harmful message or downloading a file or a fake update. Regrettably, during the moment of infection and after the malware is downloaded in the system, no signs can be detected of its presence. Having  reliable security software, in most cases, is the only way to search the whole operating system for hidden malicious code and catch the Trojan horse on time.

The Resmon.exe Virus

Most people infected with Trojans such as the Resmon.exe virus can become victims of data theft, system hacking, unauthorized system and software changes, irreparable OS damage, removal or modification of important files and similar harmful effects. The offenders who stand behind the Resmon.exe virus infection can program it to perform different criminal activities.

For instance, they can set it to locate and exploit system vulnerabilities so that Ransomware, Spyware or other malware can later on be snuck into the system.

  3. Select Resmon from the list and click on Uninstall.
  4. Follow the steps in the removal wizard.

If you have a Mac virus, please use our How to remove Ads on Mac guide.

If you have an Android virus, please use our Android Malware Removal guide.

If you have an iPhone virus, please use our iPhone Virus Removal guide.

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 Resmon.
  • If you find any of the programs suspicious then uninstall them if they turn out to be linked to Resmon.
  • 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 Resmon 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 Resmon 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 the malware 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 Resmon 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 Resmon extension
  4. Get rid of Resmon 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 the malicious program or another unwanted app, change it to an address that you’d want to be the browser’s new-tab page.

How to Delete Resmon

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

    • 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 Resmon in the Registry, go manually to the following directories and delete them:

    • HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Run/Random
    • HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Main/Random

    What is Resmon.exe?

    Resmon.exe is a file with an executable name, but malicious actors are employing it to camouflage their malevolent software. It is important to be aware that it has the potential to cause damage to the computer system, hence it is advisable to promptly eliminate it. The worst aspect of infections like Resmon and BBWC is that the victims, in many cases, do not know that they have been contaminated and that a harmful activity is running in the background of their system. The absence of symptoms helps threats like Resmon remain hidden and perform their criminal agenda without interruption.


    Is Resmon virus dangerous?

    Security experts advise that if you have even a slight suspicion that a Trojan has sneaked inside your computer, you should immediately scan the system with professional malware removal software and remove anything that gets detected as harmful or potentially unwanted. The reason is, if not detected on time, a single Trojan Horse can severely damage the entire computer, steal important information, destroy valuable data and even invite other viruses inside the computer. That is why we described manual steps for finding and removing the infection in the removal guide below.
    Completing the manual steps, however, may require some computer literacy and can hide a risk for your system’s safety if not repeated correctly. This is why we suggest that users who do not rely on their computer skills should not experiment to remove Resmon manually, but use a professional removal tool of their choosing. If you don’t have such a tool at hand, there is a trusted program that can help you deal with Resmon which is available in the removal guide that follows.
