When I first got my desktop computer, a friend of mine suggested that I download Malwarebytes to serve this purpose and better protect my device. I have always appreciated the extra layer of security, and have performed many scans of my computer over the years using Malwarebytes.

However, I've never looked into how it actually works. When Malwarebytes conducts a scan of a computer, what evidence or clues does it look for to detect a virus? Does it scan files, code, or application data? And if it does discover problematic results, what does it do to remedy the problem? It is interesting to me that the term "virus" has become regular vernacular, yet most people don't actually understand what a virus is, or how they can be resolved (myself included).
