"Employee Retention Credit email virus" removal guide
What is the "Employee Retention Credit" scam email?
"Employee Retention Credit email virus" refers to a spam campaign proliferating the TrickBot trojan. The term "spam campaign" defines a mass-scale operation during which deceptive emails are sent by the thousand. The scam letters distributed through this campaign - are disguised as notifications from the IRS (Internal Revenue Service) - the United States main body of federal statutory tax law, responsible for collecting taxes and administering the IRC (Internal Revenue Code). The fake IRS emails notify of renewed taxation policies for business - issued in response to the COVID-19 pandemic. The amended policies are supposedly contained in an attached Microsoft Office Excel document. However, upon opening, the file initiates download/installation of TrickBot malware.
The "Employee Retention Credit" scam emails (subject/title "IRS Documentation Policies Renewal"; may vary) mention the genuine business relief measure - "The Employee Retention Credit"; it is a fully refundable tax credit that eligible employers who are able to keep employees on payroll can claim. The fake IRS letters notify of a renewal in business taxation policies. Details concerning these changes can be found in the virulent attachment ("Info_76762.xlsb"; filename may vary). Furthermore, the emails state that the document can only be opened on PCs (personal computers) - due to alleged security measures. It can also be opened through any Internet browser, with the exception of Microsoft Edge and Internet Explorer. As mentioned in the introduction, the "Employee Retention Credit" emails are fake, and they are in no way associated with the real Internal Revenue Service. Therefore, instead of accessing the promised information, when the attached Excel document is opened and macro commands are enabled - TrickBot's infection process is triggered.
The TrickBot trojan is a versatile piece of malicious software, primarily geared towards data-theft. Some of its main functionalities include - gathering system information, extracting saved log-in credentials (i.e., IDs, usernames, and passwords), Internet cookies, browsing activity, auto-fills, and other sensitive data from certain browsers. This malware is also capable of altering displayed websites so that data entered into them (e.g., log-in credentials) would be recorded and delivered to the cyber criminals. TrickBot can obtain PIN codes of several US telecommunication service providers from users' devices, which allows the criminals to use victims' phone numbers. Additionally, newer versions of this trojan can operate as screen-locking ransomware. In other words, the malicious program can lock the infected device's screen and demand payment for access recovery. To summarize, by trusting the fake "Employee Retention Credit" emails, users can experience system infections, severe privacy issues, financial losses, and identity theft. If it is suspected/known that TrickBot (or other malware) has already infected the device - it is crucial to immediately remove it with the use of anti-virus software.

How to avoid installation of malware?
To avoid infecting the device via spam mail, it is advised against opening suspicious and irrelevant emails - especially any attachments or links present in them. It is recommended to use Microsoft Office versions released after 2010. Malware is not proliferated exclusively through spam campaigns; it is also distributed via untrustworthy download channels (e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, etc.), illegal activation ("cracking") tools, and fake updates. Therefore, it is important to only download from official and verified sources. Additionally, all programs must be activated and updated with tools/functions provided by legitimate developers. It is paramount to have a dependable anti-virus/anti-spyware suite installed and updated. This software has to be used to run regular system scans and remove detected threats and issues. If you've already opened "Employee Retention Credit 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.
