BID PURCHASE DOCUMENT removal guide
What is BID PURCHASE DOCUMENT?
"BID PURCHASE DOCUMENT" is a spam email campaign used to proliferate a trojan-type virus called FormBook. It is very similar to Swisscom Email Virus, Complaint Email Virus, AT&T Invoice Email Virus, and many others. As usual, criminals send hundreds of emails that contain deceptive messages encouraging users to open attachments, however, the attached Microsoft Office documents download and install malware - opening them results in infiltration of FormBook.
"BID PURCHASE DOCUMENT" campaign's emails contain a message encouraging victims to make a bid. For more information, users are encouraged to open an attached MS Office document. This is a scam. The opened document immediately installs FormBook onto the system. Note that the deceptive email contains the signature of an engineer from "Addax Engineering Co. Ltd", however, this is another deceptive ploy. Cyber criminals often claim to be employees of legitimate companies (typically major ones) or governmental agencies. In this way, they attempt to give the impression of legitimacy, thereby increasing the number of infections. Users are much more likely to open files that are received from familiar names. With regard to FormBook, this is a high-risk trojan designed to record sensitive information. The capabilities of this malware are significant - it can collect clipboard data, saved logins/passwords, take screenshots, track web browsing history, and so on. In addition, FormBook accepts commands from a remote Command and Control (C&C) server to perform various actions (e.g., reboot/shutdown the system, download files, etc.). Cyber criminals might gain access to victims' personal accounts (e.g., banks, social networks, etc.), and infect and exploit the system. Therefore, the presence of FormBook can lead to serious privacy issues, significant financial loss, and computer infections. You can read more about FormBook in this article. If you have recently opened the "BID PURCHASE DOCUMENT" campaign attachment, your computer is likely to be infected. We advise you to scan it with a reputable anti-virus/anti-spyware suite and eliminate all threats.

There are many trojans similar to FormBook. The list of examples includes (but is not limited to) Hancitor, LokiBot, Adwind, and TrickBot. These trojans are also likely to be distributed using spam campaigns. As with FormBook, most trojans record sensitive information. In some cases, however, these viruses proliferate other malware (typically ransomware). In summary, trojans pose a direct threat to your privacy and computer safety - they should be eliminated immediately.
How did BID PURCHASE DOCUMENT infect my computer?
"BID PURCHASE DOCUMENT" emails come together with a malicious Microsoft Office document. Once opened, this attachment encourages users to enable macro commands and/or notifies that the file might be linked to others. By complying, users inadvertently grant these files permission to infiltrate FormBook into the system. Although distributing malware using MS Office documents is a simple and effective method, it has a major flaw. Malicious documents are only able to infect the system if the user opens them using tools from the Microsoft Office suite. For example, if .doc files are opened using applications other than MS Word, malware will not be infiltrated. In addition, FormBook targets only the Microsoft Windows Operating System and, therefore, users of other platforms are safe.
How to avoid installation of malware?
Poor knowledge and careless behavior are the main reasons for computer infections. Caution is the key to safety. Therefore, pay close attention when browsing the Internet. We strongly recommend that you think twice before opening email attachments. Files that seem irrelevant or have been received from suspicious/unrecognizable email addresses should never be opened. Furthermore, download your software from official sources only (using direct download links) and keep installed applications up-to-date. Using a reputable anti-virus/anti-spyware suite is also paramount, since these tools can eliminate malicious files before the infection starts. If you have already opened the "BID PURCHASE DOCUMENT" attachment, we recommend running a scan with Malwarebytes 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 the "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 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.
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.
