A virus was a biological disease-causing agent, although the term itself could also apply to a malicious technological computer program.

The Faction Paradox, for example, introduced a virus into the Third Doctor as he regenerated altering his biodata. (EDA: Interference: Book One)
Another virus originated from a mutation in a mood drug in the upper levels of New New York in New Earth, this one, however, was airbourne. (DW: Gridlock)
