Not a problem … no internet, no risk, no need for anti-virus or updates, just leave it alone!
If you disable anti-virus etc. completely the machine will run a whole lot faster

Extremely unlikely, for several reasons.
Pentax cameras, especially, are in relatively small numbers, so it's unlikely anyone would want to bother writing code for such a small user base.
Other than for firmware updates, the camera is effectively a read-only device, so getting any malevolent code onto a camera would likely be difficult.
However, it is possible that one or more of your cards could be infected, the infection having come from a computer at some point and is being "re-transferred" back again … not an issue I've ever been aware of, but possible.
To prevent this occurring in the future, the card(s) should be write-protected except when in the camera.
I will emphasise, these are extreme circumstances, purely conjecture, with no basis in my experience
Much more likely that your older software is having problems indexing or opening files from the camera and corrupting them at this point.
It is quite possible that if only the EXIF data has been damaged another image viewing program will be able to open the images … try IrfanView, it'll open most things
