You bought a smart TV, set it up in the living room, and now it streams everything from Netflix to YouTube without a hiccup. Life is good. But here’s the thing most people don’t think about until it’s too late: that TV is a computer. It runs an operating system, connects to your home network, and can download apps. And where there are apps and internet connections, there are bad actors looking for a way in.
This guide covers what smart TV antivirus software actually does, what to look for when you’re shopping for it, and which products are worth your time in 2026.
Do Smart TVs Actually Get Viruses?
Short answer: yes, especially if they run Android TV. Android TV is basically Android on a bigger screen, which means it shares the same attack surface. Malicious apps, adware, and even ransomware have all been documented on Android-based smart TVs. Samsung’s Tizen OS and LG’s webOS are less targeted, but they’re not immune either.
The Reddit antivirus community gets this question constantly, and the consensus is pretty consistent: if your TV runs Android TV or Google TV, treat it like you’d treat an Android phone. That means being selective about app installs and, yes, considering a security app.
But here’s where it gets nuanced. Not all smart TVs support third-party security software. Your options depend heavily on which OS your TV runs.
Which Smart TVs Can Actually Run Antivirus Software
This is the first thing you need to check before buying anything.
- Android TV and Google TV (Sony, Philips, Nvidia Shield, TCL, Hisense on Android): Full Google Play Store access. You can install dedicated smart TV antivirus apps like ESET Smart TV Security directly.
- Samsung Tizen OS: No third-party antivirus support. Samsung has its own built-in security scanning. Your best bet is securing the network level instead.
- LG webOS: Same situation as Tizen. No third-party AV apps available through the LG Content Store.
- Roku OS: Closed platform. No antivirus apps. Network-level protection is your only real option here.
- Fire TV (Amazon): Runs a forked version of Android. Limited antivirus options, but some apps can be sideloaded.
If your TV runs Android TV or Google TV, you have the most options. If it runs anything else, skip straight to the network-level protection section below.
What to Look for in Smart TV Security Software
Smart TVs have limited processing power compared to a laptop or desktop. A security app that hammers the CPU will make your TV sluggish, cause buffering, and generally make your streaming experience miserable. So performance impact is the first thing to evaluate.
Beyond that, here’s what actually matters:
- Compatibility with your TV’s OS version: Check the app’s minimum Android TV version requirement against what your TV actually runs. Some older TVs are stuck on Android 8 or 9 and can’t run newer security apps.
- Real-time protection: Scheduled scans are fine, but real-time protection catches threats as they happen rather than after the damage is done.
- Malware and adware detection: Adware is the most common threat on smart TVs. Make sure the product explicitly covers it.
- Low resource usage: Look for products that advertise lightweight operation or are specifically designed for Android TV environments.
- Multi-device licensing: If you’re already paying for antivirus on your PC or phone, check whether your existing subscription covers Android TV devices. Many do, and you’d be doubling up unnecessarily.
Recommended Products for Smart TV Protection
These two products cover the main approaches to smart TV security in 2026. One is purpose-built for the Android TV environment, and the other is a comprehensive suite that extends coverage to your TV as part of a broader home security package.
ESET Home Security
ESET has a dedicated Android TV app called ESET Smart TV Security, and it’s one of the few antivirus products that was actually designed with the TV interface in mind. It’s available on Google Play, it runs light, and it covers real-time protection against malware and ransomware. Over 110 million people use ESET products globally, which tells you something about the detection quality behind it.
ESET Home Security is mid-range on pricing, which makes it a solid value given the detection quality you’re getting. It covers multiple devices, so your TV, phone, and PC can all sit under one subscription. The one gap worth noting: there’s no iOS antivirus component if you’re an iPhone household, but for Android TV specifically, it’s a strong fit.
Bitdefender Total Security
Bitdefender consistently tops independent lab test rankings, and Total Security is their flagship multi-device suite. It covers Android devices including Android TV, and it brings a full stack of protections: real-time threat detection, anti-phishing, network threat prevention, and more.
It sits at a premium price point, but if you want the best detection rates available and you're protecting a household full of devices, the per-device cost works out reasonably. Bitdefender is also known for extremely low performance impact, which matters a lot on a TV's limited hardware.
Network-Level Protection: The Backup Plan for Non-Android TVs
If your TV runs Tizen, webOS, or Roku, you can't install an antivirus app directly. But you're not completely out of options.
Router-level security is your best alternative. Several routers now come with built-in threat intelligence that blocks malicious domains before they ever reach your TV. Brands like Asus, Netgear, and Eero offer this through subscription services or built-in firmware features. It's not the same as on-device protection, but it catches a meaningful percentage of threats at the network entry point.
And regardless of what TV you own, these habits make a real difference:
- Only install apps from the official app store for your TV's platform
- Keep your TV's firmware updated, manufacturers push security patches this way
- Disable features you don't use, like the built-in camera or microphone if your TV has them
- Put your TV on a separate guest network so a compromised TV can't reach your laptops and phones
Can a smart TV get a virus from streaming services like Netflix?
Streaming services themselves are not a meaningful infection vector. The risk comes from installing apps outside official stores, visiting sketchy websites through the TV's browser, or connecting infected USB drives. Netflix, Disney+, and similar services are safe to use.
Does ESET Smart TV Security work on all Android TV brands?
It works on any device running Android TV with a compatible OS version. That includes Sony, Philips, Hisense, Nvidia Shield, and TCL models on Android TV. It does not work on Samsung, LG, or Roku platforms.
Is free antivirus software available for smart TVs?
A few free options exist on Google Play, but the detection rates and feature sets are significantly weaker than paid options. For a device connected to your home network, the small cost of a paid subscription is worth it.
Key Takeaways
- Android TV and Google TV devices can run antivirus apps. Samsung, LG, and Roku platforms cannot.
- Performance impact matters. Choose a product designed for limited-resource devices or one with a documented low footprint.
- Check OS compatibility before buying. Your TV's Android version must meet the app's minimum requirements.
- ESET Home Security is the go-to for dedicated Android TV protection at a mid-range price with strong detection quality.
- Bitdefender Total Security is the premium choice if you want top-ranked lab scores and coverage across every device in your home.
- If your TV can't run antivirus software, router-level security and good app hygiene are your best defenses.
- Firmware updates are not optional. They carry security patches that matter as much as any antivirus app.
Smart TV security is still a relatively young category, but the threats are real and growing as these devices become more capable. Getting the right protection in place now means you're not scrambling after something goes wrong.
