Can i ask something about why my computer does not get viruses?

For your first question: You do not get viruses because you do not go to websites that can possibly put them on your computer and, from what it sounds like, you don't download any risky files or attachments from emails. I do not run any anti-virus software or anti-spyware on my computer and i've been fine for years. You just have to be careful where you go and what you download.

For your second question: Macs do get viruses, but they are way less common because there aren't as many Macs out there compared to PCs so nobody really develops viruses for them. Macs are better than PCs if you do any audio/video/picture editing, that is where they truely excel. Other than that, in my opinion, PCs are better.
