病毒 is used in both biological and digital contexts. Biologically, it pairs with verbs like 感染 (to infect), 传播 (to spread), and 变异 (to mutate). In computing, it pairs with 攻击 (to attack), 感染 (to infect), and 防御 (to defend against).

The word 毒 (poison/toxic) evokes something harmful and invasive, which makes 病毒 a memorable and apt term. Note that 细菌 (xìjūn, bacteria) is a distinct term and should not be confused with 病毒.
