I guess I am one of those Mac fanboys.
I don't run anti-virus software. Never have.
Anything installed on my Mac (or any other Mac that I know of) must have a human being type in the main password. Otherwise, no install.
Nothing, and I mean nothing, installs on a Mac without a human typing in the password.
If someone was dumb enough to install a Mac anti-virus program when one isn't needed then they get what they deserve.
My MacBook has been running perfectly for nearly four years now and just about the only time I have had to even reboot the thing was during an application installation. Otherwise it just hibernates perpetually. I surf wherever I like without any fear at all.
PC users can mock us "fanboys" all they want but we don't spend endless hours cleaning our registries, defragging our hard drives, paying for endless anti-virus subscriptions or any of the other myriad annoying things that come part and parcel with any Windows OS. I know because until four years ago I used to do that stuff. I have three Macs in the house now, two MacBooks and one iMac desktop that I use in my business. Can't wait to upgrade to Quickbooks for Mac at the end of the year.
Now I just use my computer and it just works. If that makes me a fanboy, so be it.
