Malicious Software: Viruses, Worms, and More

There are many types of malware (short for malicious software) out in the world right now. This is a general term used to encompass a variety of invasive and potentially damaging program code that attack your computer in different ways.

Malware can get onto your computer through many different channels. A seemingly legitimate download file could arrive with malicious software either built in or packaged with it. Clicking on a suspicious web link can bring you to a webpage that runs programs or scripts on your computer. If a USB flash drive has something infected on it, there's a possibility it will move to your machine if you plug it in.
