What is ADP Email Virus?

Similar to FedEx Package, eFax, Sage Invoice, and many others, "ADP Email Virus" is another email spam campaign used to distribute TrickBot malware. This campaign distributes email messages that contain various invoices (in .doc format) and encourages users to save them. Be aware, however, that these attachments are malicious - once opened, they stealthily download and install ADP Email Virus.

As mentioned above, the spam emails contain messages stating that users have received important information regarding a type of invoice. All details are stored in an attached .doc file, which users are encouraged to save. This is a scam. The attached MS Word document is malicious - it stealthily downloads and installs the TrickBot trojan. This malware poses a significant threat to your privacy. It hijacks web browsers and modifies them to record the logins/passwords of various accounts (including sensitive accounts, such as banks, PayPal, cryptowallets, social networks, and so on). Cyber criminals then misuse victims' accounts to generate revenue (via money transfers, online purchases, identity thefts, etc.) Therefore, the presence of the TrickBot trojan can lead to serious privacy issues and significant financial loss. If you have opened "ADP Email Virus" email attachments, immediately scan the system with a reputable anti-virus/anti-spyware suite and eliminate all detected threats.

There are many trojans similar to TrickBot. For example, Adwind, FormBook, and Pony. As with ADP Email Virus, these trojans are proliferated using email spam campaigns. Their behavior is also very similar - most record personal information. Some trojans are designed to inject other viruses (in most cases, ransomware) into the system. In summary, trojan-type viruses pose a significant threat to your privacy and Internet browsing safety.

How did ADP Email Virus infect my computer?

As mentioned, "ADP Email Virus" distributes a malicious MS Word document by presenting it as a type of invoice. Immediately after opening this file, users are asked to enable macro commands, otherwise the content will not be displayed properly. Once macros are enabled, the attachment executes a number of commands to download and install TrickBot. Be aware that this malware distribution method has flaws. Firstly, TrickBot is downloaded only if the victim enables macro commands and if the attachment is opened using the MS Word program. If the user opens the attachment using another app capable of reading the .doc format, the malware will not be downloaded. Secondly, TrickBot targets the MS Windows Operating System only and, therefore, users of other platforms are safe.

How to avoid installation of malware?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, it is very important to pay close attention when browsing the Internet. Think twice before opening email attachments. Files that seem irrelevant (e.g., random invoices, bills, job applications, etc.) or have been received from suspicious (unrecognizable) emails should never be opened - these emails should be deleted immediately, without reading. Having a reputable anti-virus/anti-spyware suite installed and running is also paramount (these programs significantly increase system protection). Furthermore, 2010 and newer versions of MS Office open newly-downloaded documents in "Protected View" mode, which prevents malicious executables from downloading/installing malware. Old MS Office versions lack this feature and, thus, using them is risky. If you have already opened "ADP Email Virus" attachment, we recommend running a scan with Malwarebytes 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, 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.
