Windows 7: virus, spyware, malware?

What is the difference between these various infections? Is there a real difference, or is it just a marketing technique?



In my mind, everything that infects your computer and causes undesirable results is a virus.

I think you get my point already, so I will move on. Do the various security products protect against different things? Or do MSE, Avast, and Malwarebytes just protect against infections in general?

"Malware" is a catch-all word for spyware, virus, Trojan, Rootkit, adware, worm, etc...
