"Office had a contact with a coronavirus infected people" removal guide
What is "Office had a contact with a coronavirus infected people"?
Cyber criminals behind this malspam campaign attempt to trick a recipient into believing that his/her office has been exposed to the Coronavirus and reviewing (opening) the attached document. This email contains a malicious Microsoft Excel document which is designed to cause installation on TrickBot, a trojan-type malware.
Cyber criminals send an email claiming that recipient's office had a contact with people who are infected with the Coronavirus. The main purpose of this email is to deceive a recipient into opening a malicious MS Excel document ("application_coronavirus.xls") which supposed to contain a list of infected people and allowing it to enable content/editing. Although, this document is blank and contains hidden macros that are designed to install TrickBot. TrickBot is a Trojan which is designed to steal sensitive information by hijacking web browsers and modifying opened websites. When victims enter credentials (logins, passwords, etc.) on modified websites, then TrickBot sends them to cyber criminals behind it. Additionally, TrickBot can hijack applications such as WinSCP, Microsoft Outlook, Filezilla as well. It is capable of collecting saved passwords, autofill data and other sensitive information too. In most cases malware like TrickBot is used to steal email, social networking, banking accounts, cryptocurrency wallets, and other personal accounts that could be misused to make fraudulent purchases, transactions, spread malware further, trick other people into transferring money, etc. Additionally, some versions of the TrickBot are capable of locking victim's screen. Either way, it is strongly recommended not to open the file attached to this email and enable editing/content in it. This could cause problems like monetary, data loss, identity theft, issues related to online privacy, browsing safety, and/or other serious problems.

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 filename 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 Malwarebytes for Windows.
