Samsung has advised owners of its latest TVs to run regular virus scans.
A how-to video on the Samsung Support USA Twitter account demonstrates the more than a dozen remote-control button presses required to access the sub-menu needed to activate the check.
It suggested users should carry out the process "every few weeks" to "prevent malicious software attacks".
The suggestion surprised cyber-security specialists, who said the public would be unlikely to go to the trouble.
