"Walmart email virus" removal guide

What are fake "Walmart" emails?

"Walmart email virus" is a malware-proliferating spam campaign. This term defines a mass-scale operation during which thousands of deceptive emails are sent. The letters distributed through this campaign - are presented as delivery notifications from Walmart - an American international department and grocery store chain. Despite their legitimate appearance, these emails are fraudulent and are in no way associated with Walmart Inc. Upon opening the fake payment invoice - download/installation of the Dridex malicious program is triggered.

The fake "Walmart" emails (subject/title "Invoice copy 6936415"; may vary) inform recipients that their payment has been received and their parcel will be delivered soon. Before the delivery, the scam letters request recipients to review the "payment invoice". When this Microsoft Office Excel document is opened, and its macro commands enabled - Dridex malware's download/installation is initiated.

The primary functionality of Dridex is data theft. This malicious software has keylogging abilities. In other words, it can record keystrokes. This endangers the privacy and security of typed information. Typically, keylogging is used to obtain the log-in credentials (i.e., IDs, usernames, and passwords) of various accounts and platforms. For example, finance-related accounts (e.g., online banks, e-commerce, digital wallets, etc.) can be used to make fraudulent transactions and/or online purchases. Communication platforms (e.g., emails, social networking, social media, messengers, etc.) are also of interest to cyber criminals. These accounts can be used to ask contacts, friends, or followers for loans - under the guise of the genuine owner. Alternatively, the platforms can be used to proliferate malware by sharing infectious files and/or links to malicious websites. To summarize, by trusting the fake "Walmart" emails, users can experience system infections, severe privacy issues, financial losses, and even identity theft. If it is known or suspected that Dridex (or other malware) has already infected the system - an anti-virus must be used to remove it immediately.

"Spring Marine Management S.A.", "Romanian Post", "Employee Retention Credit", and "KIO KOREA" are some examples of malware-spreading spam campaigns. The emails distributed through these large-scale operations are usually presented as "urgent", "important", "priority", and/or disguised as mail from real companies, institutions, organizations, authorities, and other entities. Aside from distribution of malicious software, scam letters are used to facilitate phishing and other scams. Regardless of what these emails promise, offer, request, or demand, the end-goal is the same - to generate revenue for the scammers/ cyber criminals behind them. Due to the prevalence of spam mail, it is recommended to exercise caution with incoming emails.

How did "Walmart email virus" infect my computer?

Systems are infected via malicious files distributed through spam campaigns. Infectious files can be attached to the emails, and/or the letters can contain download links of malicious content. Virulent files can be in various formats, e.g., Microsoft Office and PDF documents, archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), JavaScript, and so forth. When the files are executed, run, or otherwise opened - malware download/installation is jumpstarted. For example, Microsoft Office documents cause infections by executing malicious macro commands. This process begins the moment a document is opened in Microsoft Office versions released prior to 2010. Later versions have "Protected View" mode that prevents automatic execution of macros. Instead, users are asked to enable editing/content (i.e., macro commands) and warned of the potential risks.

How to avoid installation of malware?

To avoid infecting the system via spam mail, it is advised against opening suspect and irrelevant emails - especially any attachments or links present in them. It is recommended to use Microsoft Office versions released after 2010. Malware is not spread exclusively through spam campaigns, it is also distributed via dubious download channels (e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders), illegal activation ("cracking") tools, and fake updates. Therefore, it is important to use only official and verified download sources. Additionally, all programs must be activated and updated with tools/functions provided by legitimate developers. It is crucial to have a dependable anti-virus/anti-software suite installed and kept updated. This software has to be used to run regular system scans and remove detected threats and issues. If you've already opened "Walmart 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.
