Samsung says you should run an antivirus scan on your Samsung smart TV "every few weeks". The society McAfee has added antivirus to its TVs recently. But do you really need to manually run an antivirus scan on your TV ?!
No, do not run antivirus scans on your TV
Let's get right to the point: no, we do not recommend running an antivirus scan on your smart TV.
If Samsung thinks you need to manually run antivirus scans on its smart TVs to stay safe, it's a good argument for not buying a Samsung TV. If you have a Samsung TV, it's a good argument to disconnect your Samsung TV from Wi-Fi and using a broadcast device such as Roku, Apple TV, Fire TV, or Chromecast.
If Samsung wants to integrate antimalware analysis in the background to check a box in a list of features and allow customers to feel better, it's perfect. But asking people to manually look for malware on their TVs is simply absurd – and if they have to do it, Samsung has done something very wrong.
The official Samsung support Twitter account has since deleted its tweet, but it is still available on the Internet Archives– and the company's QLED TVs still have built-in antivirus software. The antivirus scan is available in the menu> General> System Manager> Smart Security.
But can your TV get malware?
Smart TVs may be compromised, but this is likely to result from a zero-day attack that the antivirus will not detect.
Like all Internet of Things devices – devices connected to the Internet that are often not supported long enough with security patches – your TV's "smart" software may end up old, uncorrected, and open to attack.
If you're using an old smart TV, perhaps with an old, uncorrected Android TV software, you may have a problem. However, we recommend that you do not use the antivirus software. You can not even use antivirus software on most TVs!
Simply disconnect the TV from your Wi-Fi network and use a Roku or similar broadcast device instead. If your TV is not connected to the Internet, everything is fine. And broadcast devices such as these will continue to be supported with security and feature updates long after the manufacturer of your TV has forgotten your TV.
After all, when did you hear about the antivirus software for Roku for the last time?
