There is no reason to have an antivirus program. That only happens to other people.

This type of thought happens more than you can imagine. Usually, tech savvy people will fall under this category because they know how to avoid infections and surf safe (mostly), but there are still others who are not as savvy that feel this way until it is too late.

Typically, interactions with these people go as follows:

Me: Looks like you have a virus.
Them: How the heck did I get a virus?
Me: (tells them the ways that they can get one and that they should use antivirus)
Them: Well that (insert pre-loaded antivirus here) program kept popping up asking me to renew but I did not think it was anything I needed. So you think I should renew it?
Me: Yes, or use (redacted to avoid antivirus flame wars...right. Like anyone is actually reading this).
