A trojan is a type of malware that looks like a harmless file that’s attached to an email or gets downloaded when you click a link. Opening it installs the malware on your system. The newly installed trojan then operates in the background, executing its malicious plan of action without the user knowing. Trojans can steal passwords, delete important files, and allow attackers to access your computer remotely or disrupt your computer’s security systems.

Homer’s epic “Iliad” tells of how the Greeks defeated the city of Troy. They built a large wooden horse and left it at the city gates, then pretended to board their ships and leave. The Trojans mistakenly thought the horse was a parting gift, pulled it into the city and partied all night. Greeks hiding in the horse sneaked out, opened the gates for their armies, and that was the end for Troy. And that is how a trojan malware works.
