I recently switched to a Chromebook, and these things are virtually virus proof because there's really no hard drive to speak of. Everything is stored in "the cloud."
Now it's basically useless if you don't have a wireless connection. But it's 2014. Who doesn't have a wireless connection?
And of course I still have an HP all-in-one that I use as a desktop, and on that one I use a basic Norton package that I picked up at Best Buy. Anything more tech savvy than that is beyond my comprehension.
