That archive file contains a malicious JavaScript file designed to install Agent Tesla. This software is a legitimate RAT. However, it is quite popular among cybercriminals who misuse it for malicious purposes.

Agent Tesla can be used to record keyboard input (log keystrokes), steal login credentials, data from email, messaging clients, particular FTP, VPN clients, and download managers. Also, it can be used to prevent users from accessing Task Manager, Registry, executing commands via the Command Prompt. Therefore, Agent Tesla could be misused to steal usernames, email addresses, passwords, credit card details, and other information that could be used to steal identities, make fraudulent purchases, transactions, send malspam, trick other users into making money transactions. Therefore, the contents of the archive file that is attached to this email must not be opened.

More malspam examples are "Cobra Industrial Machines Email Virus", "Payment Schedule Email Virus", "Burofax Online Email Virus". It is important to mention that in most cases malspam emails are disguised as official, important letters from legitimate, well-known companies, organizations or other entities. In one way or another, files or links in such emails should never be opened.

How did "METZA email virus" infect my computer?

File attached to this email a 7z archive file that contains a JavaScript (JS) file which, if executed, installs Agent Tesla. More examples of files that can be used to deliver malware via malspam are other archive files like ZIP, RAR, PDF, Microsoft Office documents, executable files (like .exe). Malicious MS Office documents install malware when they get a permission to enable editing/content (malicious macros commands). Although, when users open such documents with older MS Office versions (that were released prior to the year 2010), then those documents install malware automatically. It is because never versions open potentially malicious files in "Protected View" mode.

How to avoid installation of malware?

Files and programs should be download from official websites and via direct download links. Examples of unreliable sources, tools for downloading or installing software are unofficial pages, third party downloaders and installers, Peer-to-Peer networks. Files in irrelevant emails that are received from unknown, suspicious addresses should not be opened. Any installed software has to be activated or updated using tools, implemented functions from its official developers. Third party tools tend to be designed to infect computers with malware, and it is not legal to use such tools for licensed software activation. The operating system should be scanned for malware regularly. If you've already opened "METZA email virus" attachment, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

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.

searching for malware file on your computer

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.
