As for me, what I do is use Linux.
Linux's software installation model prevents you from getting infected by malware and viruses.
This almost true.
It is more accurate to say that Linux' software installation model
insulates you from infections. It doesn't prevent it, and a poor decision by a computer's user will always bypass even the most strict security model.
There is no automated system capable of preventing a user from being tricked.
I've been wondering about this. I've tried both, Ubuntu and Windows, and Ubuntu would take getting used to for beginners, but it is
pretty easy. People had to get used to Windows 8, same deal.
If 75% of people decided to switch to Ubuntu (if they weren't already using it), would there be a way for hackers to start targeting them, as they always target the majority of users to get the most bang for their buck, so to speak.
How hard would it be, for the hackers to start targeting Ubuntu users if a bunch of newbies to Linux started to use it (Because they heard it was fool-proof)?
