Company Complaint Email Virus removal guide
What is Company Complaint Email Virus?
"Company Complaint Email Virus" is a spam email campaign similar to Microsoft Rights Management Email Virus, PayPal Email Virus, and many others. Cyber criminals use this campaign to proliferate a trojan called TrickBot. As usual, cyber criminals send thousands of deceptive email messages that encourage users to open malicious Microsoft Word documents that stealthily download and install TrickBot into the system.
The message essentially states that Companies House suspects fraud and, therefore, users are encouraged to view all information within the attached document. Be aware, however, that this is an attempt to trick users into opening the attachment, which infects the system. Companies House is a UK governmental agency and has nothing to do with this spam campaign. Cyber criminals are often disguised as legitimate companies/organizations or governmental agencies. In doing so, they increase the amount of infections proliferated, since users are much more likely to open files that are received from familiar names. TrickBot is an information-tracking trojan. After system infiltration, it hijacks browsers and modifies visited websites so that users' entered login and password details are saved on a remote server controlled by TrickBot's developers. These people might gain access to victims' bank accounts, social networks, and so on. Their aim to generate as much revenue as possible, and so there is a high probability that the criminals will misuse these accounts. Therefore, the presence of TrickBot can lead to serious privacy issues and significant financial loss. If you have recently opened "Company Complaint Email Virus" campaign attachments, your computer is probably infected with the TrickBot trojan. Therefore, you should scan it with a legitimate anti-spyware/anti-virus suite and remove all detected threats.

Company Complaint Email Virus shares many similarities with dozens of other trojan-type viruses that are also distributed using spam email campaigns. For example, FormBook, Adwind, Emotet, etc. Although most of these viruses are also designed to gather information, in some cases, trojans proliferate other viruses (e.g., ransomware). All pose a significant threat to your privacy and computer safety, and thus should be eliminated.
How did Company Complaint Email Virus infect my computer?
"Company Complaint Email Virus" proliferates a malicious Microsoft Word document that, once opened, asks users to enable macro commands, otherwise the content will not be displayed properly. By enabling macros, however, users grant these attachments permission to run commands that download and install TrickBot. Note that this spam campaign targets the Microsoft Windows Operating System only and users of other platforms are safe. Furthermore, although this malware distribution method is simple and effective, it has a significant drawback. Malicious attachments are only able to download TrickBot if they are opened in Microsoft Word. If the .doc file is opened using other app capable of reading this format, malware will not be downloaded.
How to avoid installation of malware?
Have a reputable anti-virus/anti-spyware suite installed and running. Carefully study all emails received and attachments - files that seem irrelevant or have been received from dubious websites should never be opened. We strongly recommend that you download your programs from official sources only and keep installed applications up-to-date. The main reasons for computer infections are poor knowledge and careless behavior - the key to safety is caution. If you have already opened the "Company Complaint Email Virus" attachment, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

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 file 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.
