What is "Transfast Email Virus"?

"Transfast Email Virus" is yet another spam email campaign used to spread the Ave Maria trojan. Cyber criminals send hundreds of thousands of deceptive emails encouraging recipients to open an attached "payment slip". In fact, the file is malicious, and opening it leads to a malware infection.

Transfast Email Virus

The spam email is presented as a payment notification from the Transfast company. Be aware, however, that this is merely a scam. Transfast is a legitimate company and certainly has nothing to do with this spam campaign. Cyber criminals often claim to be employees of reputable companies and governmental agencies in attempts to give the impression of legitimacy - recipients are much more likely to open attachments received from familiar names. The attachment is presented as a payment slip document, however, it is an archive file containing a malicious executable. Once opened, this executable injects the Ave Maria trojan into the system. Ave Maria is high-risk trojan designed to steal various data and cause "chain infections" (proliferate additional malware). These trojans usually gather extremely sensitive information, such as logins/passwords, banking information, and so on. The data is later misused to generate revenue (e.g., via online purchases, money transfers, borrowing money from the victim's accounts in social networks, etc.). Therefore, victims might lose savings and accrue significant debt. Additionally, the presence of Ave Maria can lead to various other malware infections (e.g., ransomware, cryptominers, and similar). Most ransomware infections compromise stored data, while cryptominers misuse system resources to mine cryptocurrencies, thereby significantly diminishing system performance. In summary, the presence of Ave Maria can lead to serious privacy issues (including identity theft), significant financial/data loss, and other problems. If you have already opened attachments distributed through the "Transfast Email Virus" spam campaign, scan the system with a reputable anti-virus/anti-spyware suite and eliminate all detected threats.

There are many spam campaigns that spread infections and share similarities with "Transfast Email Virus". The list of examples includes "FedEx Express Email Virus", "Hydrotech Email Virus", and "Managing Director Email Virus". These spam campaigns are commonly used to proliferate high-risk trojans such as TrickBot, Hancitor, FormBook, and Emotet.

How did "Transfast Email Virus" infect my computer?

As mentioned, the "Transfast Email Virus" spam campaign proliferates malware through a malicious attachment. The attached file is an archive, which contains an executable (.exe). Once executed, this file immediately injects the Ave Maria trojan, however, note that other spam email campaigns might use other file formats such as Microsoft Office documents (the most popular), PDFs, and so on. Malicious MS Office documents inject computers using macros. Once opened, these documents ask users to enable macro commands, which are then used to download and install malware. In any case, user interaction is necessary for these spam campaigns to be successful. Unopened attachments will never be able to infect systems.

How to avoid installation of malware?

The main reasons for computer infections are poor knowledge of these threats and careless behavior. The key to safety is caution. Therefore, pay attention when browsing the internet. Handle all email attachments with care. Files/links received from suspicious/unrecognizable email addresses should never be opened. The same applies to attachments that are irrelevant or do not concern you. Bear in mind that criminals often send emails with messages that are clearly too good to be true (e.g., you have won a million dollars, someone has transferred money to your bank account, etc.). Never fall for these scams. Malicious attachments typically come in the format of MS Office documents. Therefore, we strongly advise you to use 2010 or later versions of MS Office, since older versions are not implemented with "Protected View" mode, which prevents documents from automatically executing macros. Having a reputable anti-virus/anti-spyware suite installed and running is also paramount. These tools detect and eliminate malware before the system is harmed. If you have already opened the "Transfast Email Virus" attachment, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check 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".

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 Spyhunter for Windows.
