What is "TOA Vietnam Co. email virus"?
"TOA Vietnam Co. email virus" refers to a malware-proliferating spam campaign. This term defines a mass-scale operation during which deceptive emails are sent by the thousand.

It must be emphasized that the spam emails are in no way associated with the genuine TOA Corporation. The aim of this campaign is to infect recipients' devices with the FormBook malware. This malicious program poses a significant threat to device integrity and user privacy.

The fake "TOA Vietnam Co." emails (subject/title "NEW INQUIRY: 202107285 & 202107312 for TOA Vietnam Co., Ltd"; may vary) request recipients to provide a quotation in accordance with the attached inquiry.

FormBook malware functionalities
Formbook malware is designed to steal information, cause chain infections, and manipulate the operating system. The malicious program's primary functionality is data theft, and it has several features for obtaining information.

Additionally, this malware can delete Internet cookies. FormBook has keylogging abilities, i.e., it can record keystrokes. Other information-stealing functions include taking screenshots and extracting data stored in the clipboard (i.e., copy-paste buffer).
FormBook can infiltrate and execute files; hence, it can download/install additional malware (e.g., ransomware, trojans, cryptocurrency miners, etc.). This malicious program is also capable of executing commands sent from remote Command and Control (C&C) servers.
To summarize, by trusting the "TOA Vietnam Co." scam emails, users can experience multiple system infections, severe privacy issues, financial losses, and identity theft. If it is suspected or known that FormBook (or other malware) has already infected the device - an anti-virus must be used to remove it immediately.

Spam campaigns in general
"Destel Group Email Virus", "Coronavirus Track And Trace Result", "Assurance Certificates", "LINPRA Email Virus", "Order Loading Information", and "GOYAL ARTS AND TOYS Email Virus" are some examples of scam emails designed to spread malware.
The letters distributed through spam campaigns are usually presented as "official", "urgent", and similar. Aside from malware proliferation, these letters are also used to facilitate phishing and other scams. Spam mail is quite widespread; therefore, it is strongly recommended to exercise caution with incoming emails and messages.

When the files are opened - malicious software download/installation is triggered. For example, Microsoft Office documents cause infections by executing malicious macro commands. This process begins the moment a document is opened in Microsoft Office versions released before 2010. Later versions have "Protected View" mode that prevents automatic execution of macros; users can manually enable macro commands (i.e., editing/content).

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 Combo Cleaner Antivirus for Windows.
