Virus, malware, ransomware — people use these interchangeably. They're not the same. Understanding the differences tells you what protection actually matters and what vendors are overselling you.
THE DEFINITIONS
Malware is the umbrella term — any software designed to damage, disrupt, or gain unauthorized access. Everything below is a type of malware.
Virus specifically attaches itself to legitimate files and spreads by replicating when infected files are opened. True viruses are less common now than in the 1990s — modern malware doesn't need to spread this way.
Ransomware encrypts your files and demands payment for the decryption key. Currently the most financially damaging category for both businesses and individuals. Once encrypted, recovery without a backup is extremely difficult.
Trojan — malware disguised as legitimate software. You install what you think is a useful tool; it installs a backdoor. Most malware infections today start this way.
Infostealer/Spyware — silently records keystrokes, captures screenshots, steals stored passwords and browser cookies. Often runs completely invisibly for months.
⚠️ Ransomware is the category that consistently puts businesses out of operation. The only reliable protection is a current backup not connected to the machine — because ransomware encrypts everything it can reach, including connected drives and mapped network shares.
