What is AZORult?
AZORult is high-risk trojan-type virus designed to gather various sensitive information. Research shows that cyber criminals proliferate this malware using spam email campaigns. The emails typically contain deceptive text to trick users into opening attached files (e.g., fake job application forms delivered in the MS Office format).
Once opened, these attachments execute a number of commands that infiltrate AZORult into the system. Older versions of AZORult were distributed using Ramnit, Seamless, and other intermediary loaders.
Spam email campaigns use a simple scam model. Cyber criminals deliver various messages encouraging users to open attached files. Furthermore, they are likely to claim to be employees of legitimate companies or governmental institutions. They continually register various domains and email addresses by including names of companies/institutions.
In doing so, they attempt to give the impression of legitimacy - it is much simpler to trick users into believing messages received from familiar names. As mentioned above, however, opened attachments stealthily download and install trojan-type viruses (in this case, AZORult). One of AZORult's main purposes is to gather sensitive data.
This trojan is capable of hijacking web browsers and recording various saved/entered data, including cookies, logins/passwords, browsing history, and so on. Research shows that cyber criminals are mostly interested in logins/passwords of cryptocurrency wallets, email accounts, FTP accounts, and XMPP clients.
This trojan can be also be configured to obtain data stored on victims' desktops. Newer AZORult's versions have been implemented with additional features, such as taking screenshots, collecting data from Jabber chat history/logs, Skype, and other similar services. This information is extremely sensitive and cyber criminals use it to generate revenue.
Therefore, the presence of AZORult trojan might lead to serious privacy issues and significant financial loss. If you have recently opened suspicious email attachments or see the "sAMsUNg" process in Windows Task Manager, there is a high probability that your computer is infected with AZORult malware.
If so, you should immediately scan the system with a legitimate anti-virus/anti-spyware suite and eliminate all detected threats.

There are many trojan-type viruses similar to AZORult including Emotet, LokiBot, and Adwind - these are just some examples from many. As with AZORult, these viruses are often distributed using spam email campaigns.
Furthermore, their behavior is generally identical - most collect sensitive information. In some cases, however, trojans proliferate other viruses such as ransomware. In any case, these viruses pose a significant threat to your privacy and Internet browsing safety.
How did AZORult infect my computer?
As mentioned above, spam email campaigns promote malicious attachments (MS Office documents). Once opened, these files encourage users to enable macro commands, otherwise the content will not be displayed correctly. In fact, enabling macros allows attachments to execute commands that stealthily download and install AZORult.
Note that this distribution method has a major flaw - attachments are unable to download malware if opened using programs other than MS Office tools. If, for example, a .doc file is opened using software other than MS Word, the malware will not be downloaded. In addition, AZORult targets only MS Windows and users of other platforms are safe.
How to avoid installation of malware?
To prevent these infections, be very cautious when browsing the Internet. Carefully analyze each email attachment received. Files that seem irrelevant or have been received from suspicious/unrecognizable email addresses should never be opened. In addition, some trojans are distributed using fake updaters and third party downloaders/installers.
Therefore, keep installed applications up-to-date. To achieve this, use implemented functions or tools provided by the official developer only. The same applies to downloading/installing software. You are advised to download programs from official sources only, using direct download links.
Third party downloaders/installers are monetized by promoting rogue apps, and thus should not be used. Having a reputable anti-virus/anti-spyware suite installed and running is also paramount. Note that 2010 and newer MS Office versions open newly-downloaded documents in "Protected View" mode.
This prevents malicious attachments from downloading and installing malware. Therefore, using older MS Office versions is risky.
The main reasons of computer infections are lack of knowledge and careless behavior. The key to safety is caution. If you have already opened an "AZORult" attachment, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Update February 19, 2020 - Cyber criminals have recently started spreading AZORult trojan with a disguise of a legitimate VPN service called ProtonVPN. Crooks have created a replica of the genuine ProtonVPN's website - protonvpn[.]com. The replica's URL address is protonvpn[.]store.
Now due to the fact that the fake website's design is completely identical and the domain is also very similar, users can be easily tricked into downloading a fake ProtonVPN installation setup. Once executed, the fake installer injects AZORult trojan into the system.

How to remove malware manually?
Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically.
To remove this malware we recommend using Combo Cleaner Antivirus for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

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 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, 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 Combo Cleaner Antivirus for Windows.
