Why would a MAC computer be less likely to be infected with a virus than a PC computer??

Windows is more susceptible because it has so many security defects. There are viruses for the Mac, but since so few people use Macs (relatively speaking), mosst virus authors go after Windows. A bigger target.

There are also several technical reasons, but the easiest answer is "Windows is full of holes."

It is very simple all pc windows based systems work on a language named c, c+ and c++ also visual basic

it is very easy to penatrate these writing codes.

As for mac os it is built differently so the common viruses

do not upload to a common mac computer. Keep in mind that with this most programs,paripherials need a special driver for mac os(operating system) that means your printer and other gadgets.
In my opinion pc's are more vulnerable to viruses etc. because there are millions upon millions of pc owners/users.

And off course by far most of the pc's are windows based.Because of this there are many more people that will create viruses that are windows based.

Perhaps MAC is a less vulnerable system than windows. But MAC has a whole less users/owners than windows. So a whole less people will create a virus that is specific for mac.
because the MAC architecture is not as open to attack as the PC format is...PC's have many back doors to enter in if you're a hacker, MACs have far fewer as their architecture is not nearly as open to other programmers.
