Malware in 2026: viruses, trojans and ransomware in detail

Published on April 26, 2026 | Translated from Spanish

In today's digital ecosystem, the traditional virus has been relegated. Malware is diversifying into seven main types, and the most common is no longer the one that attaches itself to a file. We are talking about the trojan, which tricks the user into voluntarily installing it, and ransomware, which in 2026 remains the most destructive threat.

A digital trojan and a ransomware padlock dominate a dark malware ecosystem in 2026.

Trojans and ransomware: the evolution of malicious code 🛡️

The trojan exploits user trust by disguising itself as legitimate software, making it the most common type of malware. Meanwhile, ransomware has grown by 73% between 2023 and 2025, encrypting files and demanding ransoms. The most effective defense against the latter is not an antivirus, but maintaining updated and offline backups.

The classic virus: that old guy nobody invites to the party anymore 🦠

The classic virus, the one that needs you to click on an attachment to spread, is now almost a rarity. It's like the relative who shows up unannounced and expects you to open the door. Cybercriminals prefer more direct methods: they trick you into opening the door yourself and inviting them in.
