What differences can be found between antiviruses software of computer, cell phone and digital camera?

لايوجد ربط بين الثلاثة ولكن اذا انتقل الفايروس من جهازك الى الهاتف او الكاميرة فسوف يظل بهما حتى تقوم بعمل اعادة ظبط للمصنع للهاتف او الكاميرة ثم اصلاح الكارت بعمل اسكان عليه وتنظيفة من الفايروسات

If you are asking about the difference between Computer's AntiVirus and Cellphone's AntiVirus The Answer would be that the Computer AV is programmed in a specific language like C++ but the Cellphone's Antivirus is written (programmed) in another language like Java - There is an antiviruses that support all types of scanning (mobiles,PC's,Flash Ram,Camera's) So it depends on what the AntiVirus is devoted on There is AntiVirus AntiVirus With Internet Security Trojan Hunters etc..
So every single AV has a specefic function or multiple functions sometimes.

difference is the device OS because every OS has its security  bug that viruses use
