Samsung has advised owners of its latest TVs to run regular virus scans.

Axar.az reports citing BBC.

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.

BBC News asked Samsung whether any specific threat had prompted the warning.

The company responded that it had been "posted for customers' education".

However, it also deleted the post at about the same time. The 19-second video guide had been watched more than 200,000 times.
