Re: Could my tv get a virus from adding 3rd party channels?
A virus on Roku isn't really possible as channels/apps have no access to the OS and can only run when launched by the user (i.e., can't be running in the background other than screensavers). Roku puts up a scary message when you try to install a private channel, but it's really nothing to be concerned about. I'm not saying it's impossible for a channel/app to do something nefarious, but any channel/app in the Channel Store could do the same thing as a private channel.
