Setup.rar is one of the latest Trojan horse variants to be released on the public. Setup.rar is highly dangerous and can infect most Windows operating systems.


Trojans are known to be highly stealthy and, therefore, detecting them is always a difficult task all on its own. But if you have managed to discover this threat on your computer, you can consider yourself lucky and now all you have to do is just see to its timely removal. In other words, as soon as you’re done reading this post, we encourage you to head straight to the free removal guide we have included just below. It will provide you with all the necessary steps to thoroughly clean your system of this infection. However, keep in mind that Trojans like Setup.rar can mask their components as system files, so it’s important that you don’t delete any actual system files along the way. We also have a professional malware removal program available on this page if you would rather leave the process to an automated tool designed for this job.


Detection Tool

Please follow all the steps below in order to remove Setup.rar!

How to remove Setup.rar

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

How to Delete Setup.rar

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

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

    • 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 Setup.rar 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 Setup.rar?

    Viruses like Setup.rar and Altruistics are multifaceted and can be set to achieve a pretty large scope of different malicious tasks. This is what has contributed to Trojans becoming the most numerous malware category, responsible for roughly 80% of all malicious attacks that occur across the web.
    And because Setup.rar is still so new, there isn’t sufficient data available to precisely determine what the hackers behind it are exploiting it for. Instead, we would like to offer you a glimpse of what harmful software of this type is capable of in general. And we believe that will be more than enough to convince you to get rid of this malicious variant in the quickest possible way.
    For example, Trojan horse viruses like Setup.rar are often put to use when the cybercriminals are after sensitive information like login details, passwords, financial data, etc. And Trojans have a whole arsenal of ways in which they can obtain this information, such as logging your keystrokes, allowing the hackers remote access to your computer, hijacking your traffic, tapping into your webcam and microphone and others.

    Is Setup.rar dangerous?

    Software of this type can easily disable your antivirus system and allow other malicious threats to enter your OS without you even realizing it. This is a common way of distributing ransomware viruses, for example. In addition, Trojans are also very often used to mine cryptocurrencies on the computers of their victims, and this usage has rapidly been gaining momentum as of late. But your system’s resources can be exploited for other purposes as well, such as sending out spam or infecting other computers in the same network and forming so-called botnets.
    With the above in mind, it may also be a good idea to run a full system scan of your computer after you have removed this particular variant. You never know what other malware it may have potentially introduced in the meantime.
