"Air Sea Land email virus" removal guide

What is the "Air Sea Land" scam email?

"Air Sea Land email virus" refers to a malware-proliferating spam campaign. The term "spam campaign" describes a mass-scale operation during which deceptive/scam emails are sent by the thousand. The fake "Air Sea Land" letters supposedly concern order payments. This spam mail aims to spread malicious software. Therefore, when recipients open the files attached to these emails - malware download/installation is initiated.

Air Sea Land malware-spreading email spam campaign

The "Air Sea Land" scam emails inform recipients that their payment will be released after they confirm the attached payment details. However, instead of containing any sort of payment-related information, the attachment initiates the system infection process - upon opening.

Spam campaigns spread a wide variety of malicious programs. It is noteworthy that malware can have a broad range of heinous functions, which can be in different combinations. The abilities of malicious programs classified as trojans can be particularly varied. For example, trojans can cause chain infections (i.e., download/install additional malware), exfiltrate files and extract information from the system, enable remote access/control over devices (RATs - Remote Access Trojans), obtain data from browsers and other installed applications, record key-strokes (keylogging) and/or audio and video via microphones/cameras, and so on. Ransomware encrypts data and/or locks the device's screen - to make ransom demands for the decryption/ access recovery. Cryptocurrency miners are malicious programs that use system resources (potentially to the point of permanent hardware damage) to generate cryptocurrency. To summarize, by trusting the "Air Sea Land" scam letters, users can experience multiple system infections, severe privacy issues, financial losses, and identity theft. If it is suspected/known that malware has already infected the device - an anti-virus must be used to remove it immediately.

"Contract Agreement Email Virus", "THUAN HIEP THANH Email Virus", "Pending Order Email Virus", and "Order Confirmation Email Virus" are some examples of spam campaigns that are designed to proliferate malicious software. The emails sent through these campaigns are usually presented as "urgent", "important", "priority", and/or disguised as messages from legitimate organizations, institutions, authorities, companies, service providers, or different entities. However, spam campaigns are not used just to spread malware, they are also employed to facilitate phishing and other scams. Due to how prevalent spam mail is, it is strongly advised to exercise caution with incoming emails.

How did "Air Sea Land email virus" infect my computer?

Systems are infected via virulent files distributed through spam campaigns. The files can be attached to the emails, and/or the letters contain download links of infectious content. These 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 - the infection chain is jumpstarted. For example, Microsoft Office documents cause infections by executing malicious macro commands. This process is initiated the moment a document is opened in Microsoft Office versions released before 2010. Newer versions have "Protected View" mode that prevents automatic execution of macros. Instead, users can manually enable the macro commands (i.e., editing/content), and they are warned of the potential risks.

How to avoid installation of malware?

To avoid infecting the system via spam mail, it is advised against opening suspicious and irrelevant emails - especially any attachments or links found in them. It is recommended to use Microsoft Office versions released after 2010. Aside from spam campaigns, malicious software is also distributed via untrustworthy 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 only download from official and verified sources. Additionally, all programs must be activated and updated with tools/functions provided by genuine developers. To ensure device and user safety, it is paramount to have a reputable anti-virus/anti-spyware suite installed and updated. This software has to be used to run regular system scans and remove detected threats. If you've already opened "Air Sea Land 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.
