Dupzom virus removal guide
What is Dupzom?
Dupzom is the name of a Trojan which is designed to operate as a malware downloader. It is designed to cause chain infections by downloading and executing malicious files that would infect computers with additional malware. Dupzom could cause installation of some ransomware, remote administration/access Trojan (RAT), cryptocurrency miner, or other high-risk malware. Therefore, if there is any reason to believe that a computer is infected with Dupzom or any other similar malware, then such threats should be eliminated from it immediately.
It is common that Trojans like Dupzom are used as tools to distribute various ransomware. Victims of ransomware attack cannot access their files because software of this type encrypts them with some strong encryption algorithm. Typically, cyber criminals behind certain ransomware are the only ones who have a tool and/or key that can decrypt files that were encrypted by it. Another type of malware that cyber criminals often distribute through such downloaders are various RATs. Typically, when a RAT is installed on a computer, it allows a cyber criminal behind it to control victim's device remotely. Such software allows a cyber criminal to access files, acquire login credentials (and other personal information), download and execute various files (including malicious ones), take screenshots, access webcam, microphone, and/or perform other actions. Furthermore, Dupzom could be used to install some cryptocurrency miner too. Programs of this type use computer resources (such as GPU, CPU) to mine cryptocurrency by solving complex mathematical problems. Simply said, cyber criminals attempt to infect computers with such programs so they could use them to generate revenue. Infected computers begin to work slower or do not respond at all, consume more electricity. Also, installed miner could cause unexpected system crashes/shutdowns that may cause permanent loss of some unsaved data. To sum up, having a computer infected with Dupzom can be the reason behind of installation of other malware that could cause problems like data, monetary loss, loss of sensitive information, issues related to online privacy, browsing safety, identity theft and/or other serious issues.

More examples of malware that operates similarly to Dupzom (is designed to spread other malware) are HimeraLoader, Ostap, and ZLoader. Cyber criminals behind programs of this type use them as tools to cause installation of some other malware that would help them to generate revenue in other or another way. Typically, users download and install software like Dupzom. Examples of how computers get infected with malicious software (including malware downloaders like Dupzom) are provided in the next paragraph.

How to avoid installation of malware?
It is strongly recommended not to open files (attachments) and website links that are presented in irrelevant emails and/or emails that are received from unknown, suspicious addresses. The safest option is to ignore them (leave them unopened). All files and programs should be downloaded only from official and trustworthy webistes and through direct links. Unofficial websites, third party downloaders, installers, Peer-to-Peer networks, and other channels of this kind often are used as tools to proliferate, distribute malicious files and programs. Software and operating system has to be updated and activated via implemented functions and/or tools that are designed by official developers. Third party tools can be and often are the reason behind installation of malware. Also, software that requires activation should never be activated through third part, unofficial tools because it is not legal. And finally, it is important to have a reputable antivirus or anti-spyware software installed on the operating system perform scans with it regularly. Also, such software should be always up to date. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
