What is "Inland Revenue Exchange System Email Virus"?
Typically, malspam contains phishing messages, malicious attachments, and website addresses. Cyber criminals often disguise these emails as legitimate and official by exploiting names of well-known companies and organizations. This particular malspam email is disguised as a message regarding an invoice. The cyber criminals responsible attempt to deceive recipients into opening a malicious attachment, which infects computers with a Trojan named Ursnif (also known as Gozi).
Cyber criminals behind this malspam claim that this email contains a copy of an electronic invoice. The attached Microsoft Excel file named Fattura_45456.xls (its name might differ in other emails) is malicious and installs Ursnif. Note that, this malware is installed on computers through this document only if recipients give it permission to enable editing (macros commands). Ursnif is a Trojan designed to record various user-system information, browsing data, and login credentials. It is also capable of recording keyboard input (logging keystrokes) and executing downloaded files. Cyber criminals behind this malicious program could misuse obtained information to steal identities, credit card details, various accounts, and use them to trick other people into making payments, fraudulent purchases and transactions, spreading this and other malspam campaigns further, and for other malicious purposes. Additionally, they could use Ursnif to install other malware onto the victim's computer such as a Trojan (e.g., Remote Access Trojan), cryptocurrency miner, or ransomware. Therefore, by disabling Protected View mode in the aforementioned attachment/MS Excel document, recipients might become victims of identity theft, suffer monetary/data loss, experience issues relating to online privacy and browsing safety, and other serious problems. You are strongly advised not to trust this email or execute the attached file.

How to avoid installation of malware
Do not open attachments or website links in irrelevant emails. This applies mostly to emails that are sent from unknown, suspicious addresses. Note that these emails are often disguised as official, important, and legitimate. Programs and files should be downloaded from official websites. Other sources/channels such as third party downloaders/installers, Peer-to-Peer networks such as eMule, torrent clients, unofficial websites, etc., often deceive users into installing malicious programs. Installed programs must be updated and activated with tools/implemented functions that are designed by official developers. Unofficial, third party activators/updaters often cause installation of malware. Furthermore, it is illegal to use unofficial activators ('cracking') tools to activate licensed programs. To protect your computer from damage caused by malware, regularly scan the system with a reputable antivirus or anti-spyware suite. If you have already opened "Inland Revenue Exchange System 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 "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.
