Malicious emails in general

Cybercriminals behind emails containing malicious files or links deliver malware, allowing them to steal sensitive information, identities, accounts, encrypt files, and do other things. A couple examples of similar malspam campaigns are "SAM Trading Group Email Virus", "ANSR Email Virus", and "Erweka Email Virus".

How did "Cosco Shipping Bank email virus" infect my computer?

The file attached to this email is an ARJ compressed file containing another file (or files). It could have a malicious PDF or MS Office document, executable file (like EXE), JavaScript file, another infected file in it.

Malicious MS Office documents ask for permission to enable macros commands. They do not infect computers unless users enable macros (editing/content). Malicious documents opened with MS Office released before 2010 do not ask to enable macros commands - they infect computers right away.

How to avoid installation of malware?

Do not open links or files within irrelevant emails sent from unknown or suspicious addresses. Avoid using Peer-to-Peer networks, unofficial web pages, third-party downloaders, or other sources of this kind to download files, programs. Use official pages and direct links for that.

Update and activate the installed software with tools provided by its official developer. Never use any third-party/unofficial tools for that. Have reputable security software installed on a computer and run system scants with it regularly.

If you've already opened "Cosco Shipping Bank email virus" attachment, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

Delete malware in Autoruns

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 Combo Cleaner Antivirus for Windows.
