We just bought a LDC TV and I am concerned about it. It can be connected to the Internet and all the computers on our network. We are on ATT uverse and we have installed the McAfee security package on our computers but I want to know if the Television is also protected from attack. It is a Samsung LN46B640|||Viruses only attack software. I suppose it is possible to create a virus that would attack the firmware of an LCD television but I've never heard of anything like that happening and really don't believe it would happen.|||TVs don't run MS software and nobody cares to attack them - Nothing to worry.
