Surfshark Antivirus Review 2026: Is Surfshark One Worth It?

When a VPN company decides to build an antivirus, the tech community usually reacts with a healthy dose of skepticism. Building a world-class VPN network is one thing; successfully blocking zero-day malware and competing with companies that have been hunting viruses since the 90s is another.

But that’s exactly what Surfshark has attempted with its Surfshark One bundle, which includes its dedicated Antivirus. I’ve been running Surfshark Antivirus on my daily setup for the past several months, pushing its real-time protection, scanning capabilities, and system impact to the limit.

This review is an honest look at whether Surfshark Antivirus is genuinely good enough to replace your dedicated security suite, or if it’s just an add-on to sell more VPN subscriptions.

The Quick Version

If you’re in a hurry: Surfshark Antivirus is surprisingly robust and incredibly lightweight. Because it’s bundled within Surfshark One, you are getting phenomenal value—a top-tier VPN, data breach alerts, a private search engine, and a very capable antivirus all in one app. While it lacks some advanced features like a two-way standalone firewall (it relies on your OS firewall), its malware detection rates are excellent for everyday users.

Who It’s Actually For

Surfshark Antivirus is ideal for modern internet users who want a streamlined, all-in-one privacy and security suite. If you currently pay for a standalone VPN and a separate antivirus subscription, consolidating them into Surfshark One will save you significant money and system resources.

If, however, you are a security enthusiast who loves configuring complex firewall rules or deep sandboxing environments, you might find Surfshark’s streamlined approach a bit too simplistic.

Protection & Features

Surfshark has clearly invested heavily in its underlying detection engines. Independent testers like AV-TEST have highlighted the importance of modern security tools. The antivirus provides 24/7 real-time protection, scanning files as they are downloaded, opened, or modified. It also utilizes Cloud Protect, a system that analyzes unknown files in the cloud to prevent zero-day attacks without slowing down your local machine.

Beyond traditional malware scanning, Surfshark One includes Webcam Protection to prevent unauthorized apps from spying on you, and CleanWeb 2.0, which blocks malicious sites and phishing attempts at the DNS level. When combined with Surfshark Alert (data breach monitoring) and Surfshark Search (ad-free private searching), the suite covers almost every angle of modern digital threats.

System Performance

This is where Surfshark Antivirus absolutely obliterates legacy competition. Many traditional antivirus suites feel bloated, installing numerous background services that noticeably drag down system boot times and gaming performance (if you struggle with this, check out our guide to speeding up your PC).

Because Surfshark relies heavily on modern cloud-based threat detection, the local client remains incredibly light. During full system scans, CPU spikes were minimal, and I was able to continue working on memory-intensive tasks without any system stuttering. Background scanning is practically invisible.

Pricing & Value

To get Surfshark Antivirus, you subscribe to the Surfshark One or Surfshark One+ packages. You cannot buy the antivirus entirely on its own—but honestly, you wouldn’t want to, as the value proposition lies in the bundle.

For an extra $0.50 a month over the base VPN plan, adding a capable antivirus, data breach scanner, and private search engine is an absolute steal. It is vastly cheaper than buying a standalone VPN and a separate antivirus subscription from another provider.

What I Don’t Like

The main drawback is that Surfshark Antivirus leans on your operating system for firewall duties. It doesn’t feature its own standalone two-way firewall. While Windows Defender’s built-in firewall is generally sufficient for most people, power users often prefer the granular control offered by dedicated firewall software found in premium suites from Bitdefender or ESET.

Should You Get Surfshark Antivirus?

If you are already looking for a VPN or want to consolidate your digital security into one affordable, lightweight application, yes. Surfshark One is incredibly well-priced.

The antivirus component is highly capable of stopping modern threats, and the fact that it operates without bogging down your system makes it a joy to use. It proves that a modern security suite doesn’t have to be bloated to be effective.
