Virus
From ctowiki
This is a term given to any software created with the specific purpose of harming or otherwise detrementing a computer system. Common examples are worms, trojans, and e-mailers. Do not open any e-mail attachments from anyone you do not trust very well, and even then only if you are reasonably sure they are not infected with an e-mail virus pretending to be them.
