Nothing happened immediately after the user downloaded the document, but the computer then began to respond slowly. Applications also started to crash.

Explanation
This scenario exhibits all the hallmark indicators of ransomware: delivery via a malicious email link, a delay before activation (to evade immediate detection), files renamed with an encryption extension (.enc), and a ransom note with instructions for obtaining the decryption key. A virus replicates and damages files but does not typically encrypt them for ransom. Spam is unsolicited email. Spyware silently collects user data. Ransomware's defining characteristic is encrypting victim data and demanding payment for restoration.
