How did "DUNCAN ENGINEERING LIMITED ORDER email virus" infect my computer?

This email has a malicious image with the name "DUNCAN PO ORDER.img" attached to it. It installs malware (Remote Administration Trojan named Agent Tesla) only when users/recipients download and open it. It is worthwhile to mention that cyber criminals use other file formats to distribute malware as well. It is common that they send malicious Microsoft Office, PDF documents, JavaScript files, archive files like ZIP, RAR, executable files (like .exe). In one way or another, computers get infected when users open files that are sent them via malspam. It is worthwhile to mention that when users open malicious documents with Microsoft Office version that was released before year 2010, they allow those documents to install malware automatically. Never versions include the "Protected View" mode which prevents malicious documents from installing malware. They do not install malware unless users enable editing/content (macros commands).

How to avoid installation of malware?

It is advised not to open attachments or web links in irrelevant emails that are received form unknown, suspicious addresses. Download software and files from official websites and through direct links and not to use other sources for that (e.g., Peer-to-Peer networks, unofficial pages, third party downloaders). The same applies to third party installers. Update and/or activate installed software with tools and/or by using functions that are provided by official developers. It is never safe to use various third party, unofficial tools neither to activate or update software. Besides, it is not legal to activate licensed software with such tools. Also, it is recommended to scan the operating system with a reputable antivirus or anti-spyware and do it regularly. Also, that software should never be out of date.

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.
