Viruses, Trojans & Spyware Flashcards

All 3 cards in this deck

What is a computer virus?

Malware that attaches itself to another program or file. It runs when the infected file is executed, and spreads as infected files are run or shared.

What is a trojan?

Malware that poses as a useful, legitimate program. The user is tricked into executing it, and its hidden malicious purpose then activates. It does not copy itself.

What does spyware do?

It hides on a device and logs the user's activity, such as keystrokes, then passes this to the attacker, who can use it to steal passwords or bank details.
