Just spotted this on PC World, old news to those who follow their site daily:
Unfortunately, some frames sold by Best Buy were infected with a Trojan horse. The infected units are all 10.4-inch versions, model number NS-DPF10A under Best Buy's Insignia store brand. If you don't have antivirus software and you've already plugged the frame into your PC, the malware could have spread. See Best Buy Sold Infected Digital Picture Frames for more details and a link to assistance.
That's a problem I hadn't thought of.
A virus in a piece of hardware that you don't think of as a computer on your network.
Cold this also apply to portable USB hard drives, network disk drives, cheap network disk enclosures (sans disk), network media streaming boxes (just add your own HD) ... even to a little USB key chain picture viewer ?
I guess the list is endless.
Just make sure your anti-virus software is up to date !
