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.

How to Delete Setup.rar
Open task manager
Look for the Setup.rar process
Select it and click on End task
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.
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.

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.
