I have reversed my position on this article.
Please visit, instead, this new article:
Can my computer get a virus from my camera?
OK, 99.99% no. The 0.01% “maybe” breaks down like this:
Become a Patron of Ask Leo! and go ad-free!
Memory cards as disks – memory cards used in digital
cameras can, with the right adapters, often be used almost like floppy disks in
most personal computers. It’s one way to transfer your photos from the camera
to computer. So it’s theoretically possible that any virus that could
propagate via floppy could do so via a memory card being passed around from
computer to computer.
Cameras as targets – Digital cameras are in many ways
sophisticated dedicated-purpose computers. So it’s theoretically
possible that if a camera’s “operating system” allowed programs to be loaded
into the camera somehow, such a program could be a virus.
I’ve emphasized “theoretically” in both cases above, because to my knowledge
neither have ever happened. And in my opinion neither are very likely too.
Viruses are just computer programs written by people looking for a thrill.
There are more thrills to be had, and much easier ones at that, by making
viruses for popular transmission media, like the internet, and popular computer
systems, like Windows.
In a nutshell: I wouldn’t worry about it.
