"UNICEF" email virus removal guide

What is the "UNICEF" email virus?

"UNICEF" is a deceptive email (subject: "UNICEF COVID-19 TIPS APP") designed to spread the Netwire Remote Access Trojan (RAT). This scam message abuses the current social climate (at time of writing, the coranavirus pandemic) to trick recipients into opening its malicious attachment. The attached file supposedly contains a presentation and Advanced Practice Provider tips, however, installing this file will infect the system with the Netwire RAT.

UNICEF email virus malware-spreading email spam campaign

The text presented in the "UNICEF COVID-19 TIPS APP" email states that it has attached a file, which is the presentation and APP concerning the Corona virus. In this context, the abbreviation relates to two different terms and serves two purposes. In healthcare terms, "APP" is "Advanced Practice Provider", which is inline with the aim of the scam, especially since the infectious attachment is disguised as an Excel document (which is within the archived file). The statement in the message encourages users to download and install an attached file, and hence the APP abbreviation can be interpreted (or misinterpreted) as "Application". This interpretation is furthered, as it is claims that the "APP" is updated daily (though the last word is misspelled and the message also contains other errors). Therefore, the scam's chances of success are potentially increased by users who are influenced by the message. The email states that the information will aid recipients to protect themselves and their staff respectively. It also requests that users share the email - in this way, they will unintentionally spread the Netwire Trojan. This malware is designed to give the cyber criminals behind the "UNICEF" scam email remote access and control over devices. Keylogging is a particularly dangerous capability of Netwire - it can record all information typed by individuals using the infected device. Therefore, it can steal the credentials (log-ins and passwords) of emails, social media and social networking, communication, e-commerce, banking and countless other accounts. To summarize, the Netwire RAT can cause financial loss, severe privacy issues and identity theft. Do not trust the "UNICEF" email scam. If you suspect that Netwire (or other malware) is already present on the system, use anti-virus software to remove it immediately.

Deceptive/scam emails are sent by the thousand during operations called "spam campaigns". This mail is usually disguised as "official", "important", "priority" and similar. It can even incorporate the names of legitimate organizations, companies, services and similar (e.g. UNICEF). The purpose of these message is to generate revenue for the individuals behind them. This can be done through proliferation of malware (e.g. trojans, ransomware, cryptominers and so on), however, they can carry out their purpose using other techniques. For example, these emails can attempt to steal recipients' personal information via phishing websites, or trick them into making monetary transactions (e.g. fake shipping, subscription, registration fees and other fraudulent payments), and the use of many other tactics. "COVID-19 Insurance Plan From CIGNA", "WeTransfer", "Adobe Document Cloud E-Signing", and "Secret Love" are some examples of other email scams designed to proliferate malicious software.

How did "UNICEF email virus" infect my computer?

Infections originate from the dangerous files attached to, or linked inside, deceptive/scam emails. These files can be in various formats such as archive (ZIP, RAR, ARJ, etc.) and executable (.exe, .run, etc.) files, Microsoft Office and PDF documents, JavaScript and others. When infectious files are executed, run or otherwise opened, the infection process starts (i.e., download/installation of malware). For example, MS Office documents infect systems when macro commands are enabled (i.e., editing is enabled). This process starts automatically when a malicious Microsoft Office document is opened in MS Office versions released prior to 2010.

How to avoid installation of malware

Suspicious or irrelevant emails should not be opened, especially those received from unknown/suspicious senders (addresses). Any attachments or links present in such mail must not be opened, as doing so can result in high-risk infection. Since malicious Microsoft Office documents opened in Microsoft Office programs released before 2010 immediately start the infection process, it is important to use newer versions (these have "Protected View" mode, which asks users to enable macro commands, and thus malware download/installation is not triggered when the document is opened). Malicious content also proliferates through untrusted download channels (e.g. unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders), illegal activation tools ("cracks") and fake updaters. Therefore, use official and verified download sources, and activate and update software with tools/functions provided by legitimate developers. To ensure device/user safety, have a reputable anti-virus/anti-spyware suite installed and kept up to date. Furthermore, use this software for regular system scans and removal of detected/potential threats. If you have already opened "UNICEF email virus" attachment, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

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.
