What is DocuSign Email Virus?

"DocuSign Email Virus" is another spam email campaign used to proliferate a high-risk trojan called TrickBot. Developers send thousands of emails stating that users have received a "secure" document and must review and sign it. This is a scam - the opened MS Word document will stealthily download and install the TrickBot trojan.

DocuSign Email Virus malware

The email essentially states that users must electronically sign documents, however, this is a simple attempt to trick them into opening malicious documents that download and install malware. Note that the email contains the logo of DocuSign, a legitimate company. This is very common amongst cyber criminals. They register email addresses and domains by including names of popular companies and governmental agencies. This is done to give the impression of legitimacy - it is much simpler to trick users into opening documents received from familiar names. TrickBot is high-risk trojan designed to gather personal information. Immediately after infiltration, it hijacks browsers and modifies visited website content so that entered logins/passwords are saved on a remote server controlled by cyber criminals. The criminals can then gain access to users' personal accounts (social networks, emails, banks, etc.) Therefore, the presence of a malware such as TrickBot might lead to serious privacy issues and significant financial loss. If you have recently opened emails distributed via the "DocuSign Email Virus" spam campaign, you should immediately scan the system with a reputable anti-virus/anti-spyware suite and eliminate all threats.

There are a number of trojans similar to TrickBot including, for example, Adwind, Emotet, and FormBook. Most are distributed using spam email campaigns. In addition, these viruses typically have identical behavior: they collect information. In some cases, however, trojans also proliferate other high-risk viruses, such as ransomware. In any case, these viruses pose a significant threat to your privacy and Internet browsing safety.

How did DocuSign Email Virus infect my computer?

As mentioned above, "DocuSign Email Virus" distributes a malicious Microsoft Word document that, once opened, asks users to enable macro commands. By complying, users grant permission for macro command within the document to run commands that stealthily download and install malware. This malware distribution method does, however, have a major flaw. The attachment is unable to download malware if it is opened using any software other than MS Word. If the file is opened using another app that is capable of reading .doc format, TrickBot will not be downloaded. In addition, TrickBot targets only Microsoft Windows Operating System and users of other platforms are safe.

How to avoid installation of malware?

To prevent this situation, be very cautious when browsing the Internet. Carefully analyze each email attachment received. Files that seem irrelevant and those received from suspicious/unrecognizable email addresses should never be opened. They should be deleted immediately, without reading. In addition, have a reputable anti-virus/anti-spyware suite installed and running. More recent versions (2010 and above) of MS Office open newly-downloaded documents in "Protected View" mode. This prevents malicious attachments from downloading and installing viruses. Therefore, using older MS Office versions is risky and not recommended. The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. If you have already opened the "DocuSign Email Virus" attachment, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Combo Cleaner Antivirus for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

manual malware removal step 1 Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:

manual malware removal step 4In the Autoruns application, click "Options" at the top and uncheck the "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.

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 Combo Cleaner Antivirus for Windows.
