"IRS Online Email Virus" removal guide
What is "IRS Online Email Virus"?
"IRS Online Email Virus" is categorized as a spam email campaign that is used by cyber criminals to spread the Emotet high-risk virus. The cyber criminals responsible for this campaign send an email to many users that contains a malicious attachment. The main goal of "IRS Online Email Virus" is to trick people into opening the attachment, which then infects computers with a virus.
Cyber criminals behind this campaign claim to be representatives of a federal agency, the IRS (Internal Revenue Service). Little other information regarding the email is provided, just that it contains a "Verification of Non-filling Letter.doc" document, which was supposedly sent by the 'Department of Treasure'. Cyber criminals often use spam campaigns and claim to be representatives of well-known companies (in this case, a federal agency). Using familiar company/organization names increases the probability of a successful scam and makes it easier for criminals to trick people into downloading and opening the malicious attachments (in this case, presented by the "IRS Online Email Virus" email). Note that the IRS agency has nothing to do with this scam and the attachment should never be opened. As mentioned above, this email attachment proliferates Emotet, a high-risk virus that records personal data and proliferates other viruses. This virus gathers information such as logins, passwords, and browsing activity. Having a computer infected with this virus might thus lead to privacy issues and financial loss. Furthermore, Emotet opens "backdoors" for other high-risk viruses, such as ransomware. In this way, Emotet causes chain infections.

Emotet is just one of many other trojan viruses. Other examples of similar viruses are FormBook, Adwind, TrickBot, and AZORult. These are designed to cause as much damage as possible and can lead to serious privacy (and other) issues. If any of these infections are present, we strongly recommend that you eliminate them immediately.
How did "IRS Online Email Virus" infect my computer?
Cyber criminals use many different spam campaigns. Some examples are "Pricewaterhouse Coopers", "Ernst & Young", and "BMO account report". All are very similar and are used to proliferate malicious attachments. The "IRS Online Email Virus" email contains a malicious Word (.doc) document that, once opened, requests permission to enable macros commands. Do not comply, since the attachment then downloads and installs the Emotet virus. If, however, the Word document is opened using a software other than Microsoft Office, the virus cannot proliferate. This malicious attachment targets Microsoft Windows Operating Systems only.
How to avoid installation of malware?
Be careful when browsing the web and think twice before opening any email attachment, especially if the attached file is irrelevant or the sender seems suspicious or not recognized. Having a reputable anti-virus/anti-spyware suite installed and running is also important. Trustworthy anti-spyware/anti-virus software is usually capable of detecting and eliminating malicious files before they can do any harm. If you have already opened "IRS Online Email Virus" attachment, 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 the "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 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.
