No. More than 99% of all computers are embedded systems.

That is not virus protection. By their nature they resist virus
infection, but no explicit provision for virus protection is made.

Seems unlikely.

1) The "average" person owns more cars than they do computers.
2) Modern cars can have up to 7-8 embedded computers.
3) Now add in the computers in microwaves, ovens, rice makers, etc.
4) And the ones in routers, printers etc. which are not "general-purpose
desktop computers".

I probably have more GP computers than most people and my CPU counts are:

GP comp - 5 (in 4 computers)

Routers/hubs - 2
Printer - 1

Car - At least 1, probably more
Washing machine - 1
Satellite box - 1
Digital TV box - 1
TV - probably has 1 in it

Exactly. More than 99% of all computers are embedded computers. Even
wristwatches contain computers today.

Of course it is, designing the system so it cannot run untrusted code
is absolutely virus protection, it was part of the design constraints.
