I'm new to understanding tablets and smart phones and the like, so bear with me here. I heard that it was very difficult to place a virus on a smart phone since the SP apps run in their own "environment". Also, even if a virus could be put in an app, it would be easy to delete and just reinstall the app. The idea being it is a waste of time for the hacker who is looking to do much more damage than that.. So, with this in mind, how does this relate to Surface RT and PRO? Since RT does not run Windows 8, will it have the same relative immunity from Viruses as the Smartphone does (I'm assuming what was said about the SP was correct)? Conversely, PRO running WIN8, will it have the same risk of virus infection as WIN8, 7 or XP; basically as any Windows standard OS for a PC? Of course, if the risk is that the PRO can get a virus, but RT is like a SP, then RT certainly gains a few points of attraction.. Thanks for any insight.
