HM Revenue & Customs Outstanding Amount virus removal guide
What is HM Revenue & Customs Outstanding Amount?
First discovered by My Online Security, "HM Revenue & Customs Outstanding Amount" is a spam campaign similar to You Have A Santander Secure Email. Cyber criminals employ this spam campaign to spread a trojan-type virus called TrickBot. The message states that the user has outstanding bills that have not been paid. To see all details, the victim is encouraged to open an email attachment (MS Office document). Once opened, however, the malicious attachment downloads and installs TrickBot malware.
The email is presented as an invoice from HM Revenue and Customs department. It essentially states that thousands of pounds of taxes are outstanding and encourages the user to immediately open the attached file. This is a scam. HM Revenue and Customs is a genuine UK Government department responsible for the collection of taxes and has nothing to do with this message or proliferating the TrickBot trojan. Cyber criminals continually register various email addresses and domains that contain names of legitimate companies and institutions. This is done to trick gullible users into opening random email attachments and proliferate viruses. Developers use the "HM Revenue & Customs Outstanding Amount" spam campaign to proliferate TrickBot, a high-risk trojan that hijacks web browsers and collects various logins/passwords. Developers misuse recorded information to generate revenue (through identity theft, money transfers, and so on). Therefore, the presence of malware such as HM Revenue & Customs Outstanding Amount can lead to significant financial loss and serious privacy issues. Unfortunately, discovering this malware manually is virtually impossible - developers concealing it effectively. Despite this, most reputable anti-virus/anti-spyware suites are capable of detecting and removing the TrickBot trojan. If you have already opened the "HM Revenue & Customs Outstanding Amount" attachment, we strongly advise you to run a system scan and delete all detected threats.

TrickBot shares many similarities with a number of other trojan-type viruses. The list of examples includes (but it is not limited to) FormBook, Adwind and Pony. Research shows that these are also distributed using spam campaigns. As with TrickBot, the listed trojans are also designed to gather various sensitive information. In addition, trojans often track users' browsing activity and open "backdoors" for other high-risk viruses (for example, ransomware). This behavior poses a direct threat to your privacy and Internet browsing safety.
How did HM Revenue & Customs Outstanding Amount infect my computer?
"HM Revenue & Customs Outstanding Amount" spam emails contain malicious MS Office attachments presented as tax documents. After opening this attachment, users are immediately asked to enable macro commands. This allows the attachment to download and install malware (TrickBot). Note that this will only work when using MS Office. Malicious attachments opened using other applications (capable of reading these formats) will not be able to execute rogue commands. The downloaded malware only works on the Windows Operating System and, thus, users who are running other platforms are safe.
How to avoid installation of malware?
The main reasons for computer infections are lack of knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when browsing the Internet. Think twice before opening email attachments. Files that seem irrelevant or have been received from a suspicious/unrecognizable email addresses should never be opened - these emails should be deleted without reading. Be aware that 2010 and newer MS Office versions open downloaded documents in "Protected View", thereby preventing malware download/installation. Therefore, using older versions is dangerous. Some trojans are distributed using the "bundling" method (stealth installation of rogue apps with regular software), and fake software updaters. Therefore, be cautious when downloading, updating, and installing software. Select "Custom/Advanced" options, carefully analyze each download/installation step and opt-out of all additionally-included programs. We strongly recommend that you avoid using third party downloaders/installers, since developers monetize them by promoting PUPs. Software should be downloaded from official sources only, using direct download links. The same applies to software updates. Always keep installed applications up-to-date, but use implemented functions or tools provided by the official developer only. Having a legitimate anti-virus/anti-spyware suite installed and running is also paramount. If you have already opened the "HM Revenue & Customs Outstanding Amount" 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 want 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. Make sure that you enable hidden files and folders before proceeding. If you find the malware file, remove it immediately.
Reboot your computer in normal mode. Following these steps should help to remove any malware from your computer. Note that manual threat removal requires advanced computer skills, and you are advised to leave malware removal to antivirus and anti-malware programs. Note, however, that these steps might not work with advanced malware infections. As always it is better to avoid infection than attempting to remove malware afterwards. 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.
