does the macbook pro get viruses

A point of clarification as someone is bound to make it if I don't. There are not any viruses in the wild that currently infect Macs. However, there is malware out there. The difference being that you have to actually install malware. If you download something from a questionable site and enter your password in order to install it, you give that application permission to do whatever it wants to your system, including installing utilities to monitor your activities, track your actions, etc. Most consumers consider a virus and malware to be one in the same, but folks here are quick to point out the difference. You should not assume that you can just install whatever you want without the risk of installing something that may harm your system, because you can. You do not have to worry about the types of viruses that you typically associate with a Windows machine that you may encounter just by visiting a website, etc.

The malware problem is much, much less severe on Macs than it is on Windows. You can still get into trouble if you're careless or gullible. Of course, if you run Windows on a Mac, that's no safer than running it on a PC.
