If you have physical access to the chip then yes its internal program copy protection can be circumvented. Thats not the concern here.
It's still a matter of probabilities. If your PC's OS and BIOS has been compromised, and they are connected to your PIC somehow (e.g. through USB), then there's a theoretical possibility that the PIC could end up compromised as well.

only if the PIC device has been factory shipped with a back door to access data that my application did not intend.
Sadly, this is not entirely impossible. Another article points out a different type of chip (FGPA) for which this did happen.
