In 2019, there was an event that caused a significant uproar in the consumer electronics industry. Samsung announced that Samsung Smart TVs were susceptible to virus attacks. As such, users were advised to check their devices for viruses every two weeks. The announcement attracted widespread attention and was actively discussed in the media. In response to the concerns, Samsung integrated the Smart Security feature into the menus of its TVs, giving users the ability to check their devices for malware on their own.

This raises questions about Samsung’s decision to shift the responsibility for conducting such checks to the end user, rather than automating the process. Intuitively, it may seem that automatically scanning every time the TV is turned on would be a more convenient and efficient solution. However, the company also stated that the Smart Security feature works in real-time to protect the TV from malicious attacks without active user intervention.

Are Samsung TVs infected with viruses?

The likelihood of Samsung TVs becoming infected with viruses is significantly low, which is due to a number of important technical and operational factors that distinguish these devices from ordinary computers or smartphones.

Firstly, the architecture of a Samsung TV is fundamentally different from the architecture of more common devices. The TV’s operating system is built directly into the device’s permanent memory – a chip that is not only programmed using specialized equipment, but is also soldered to the main board. This design choice inherently limits the ability to overwrite or modify the operating system in a way that would be necessary for a virus to make breaking changes. Additionally, TVs may contain semi-permanent memory chips for non-critical software updates, but they do not allow the installation of entirely new operating systems, preventing, for example, upgrading a TV from Tizen 5 to Tizen 6.

The second level of protection is due to the use of the Tizen operating system in Samsung TVs since 2015. Any potential virus would have to be specifically designed for this unique OS, a task that poses significant challenges both from a development standpoint and in terms of potential payoff. for the attacker. The specialized nature of Tizen, combined with architectural barriers to critical system modification, greatly reduces its attractiveness to potential attackers.

In addition, the ecosystem in which Samsung TVs operate provides additional protection against the introduction of malware. Applications for these devices are downloaded exclusively from the official store, where the developers are verified and known by Samsung. This controlled environment minimizes the risk of inadvertently installing malicious software. Even if a user encounters malware on the Internet, the unique operating system and technical obstacles associated with running such a virus will make it difficult to infect a TV.

How Smart Security works in Samsung TVs

Smart Security in Samsung TVs is a built-in antivirus program designed to keep your device safe in the face of ever-increasing cyber threats. This security system performs several key functions to protect your TV from malware and unauthorized changes to files and applications.

The main function of Smart Security is to scan files present on the TV to verify their integrity through checksums. Checksums are algorithmically generated values based on the contents of the file. Comparing the current checksums to the original checksums allows Smart Security to determine if files have been altered or corrupted, which could be a sign of malicious activity.

In addition to checking file integrity, Smart Security actively monitors online changes to files and applications. This includes detecting unauthorized changes that may occur as a result of malware activity. If an active application makes changes, this is considered normal behavior. However, if changes are detected in the absence of activity on the part of the application, it is considered an anomaly. In such cases, Smart Security blocks suspicious processes and notifies the user by displaying a blocking message on the TV screen.

In addition, Smart Security offers the ability to send suspicious files to Samsung servers for detailed analysis. This feature not only isolates potential threats from the user’s TV, but also enriches Samsung’s database with information about new malware, contributing to the overall level of protection for the company’s devices.

Thus, Smart Security is a multifunctional tool that takes a comprehensive approach to securing Samsung TVs, preventing unauthorized changes and blocking potentially malicious activities.

Malware on Samsung TV, how to solve the problem

A malware blocking message on your Samsung TV does not always indicate the presence of a virus. Smart Security, your TV’s built-in security system, actively monitors the integrity of files and applications. When it detects changes in checksums that may indicate file modification, the system takes steps to block the suspicious process. This is a precautionary measure designed to prevent potentially malicious activity.

Despite this, there are several reasons why a lockout message may occur that are unrelated to the presence of viruses:

  • Memory chip malfunctions: Televisions use memory chips to store data and programs. Sometimes these chips may not function properly, resulting in loss of information. If the lost data relates to a particular application, the system may interpret this as an unauthorized change, causing a warning to appear when the application is started.
  • Problems with memory allocated to Internet services: Similarly, if a portion of the memory allocated to Internet services is experiencing technical problems, a lock message may appear when you try to use those services. This is especially true when the device is connected to the Internet and the system detects that the data associated with online functionality is not as expected.

To eliminate the appearance of such messages, it is recommended that you take the following steps:

  • Reboot the TV: Simply turning off and then turning on the TV can help reset temporary errors and restore normal operation of the device.
  • Update the software: Make sure your TV has the latest version of software installed. Updates may contain fixes that improve system stability and security.
  • Factory reset: If the problem persists, resetting your TV to factory settings can help troubleshoot the software by restoring it to its original state.
