This Surfshark antivirus review covers what we found after eight weeks of testing on Windows and macOS Sequoia: detection rates, system performance, and whether Surfshark antivirus holds up against dedicated security tools — or whether it’s the kind of feature that exists mainly to justify the Surfshark One bundle price. We tested the Windows and macOS versions over eight weeks to find out.
The short version: Surfshark Antivirus detects malware well, doesn’t slow your machine noticeably, and costs almost nothing extra if you’re already paying for Surfshark VPN. If you’re looking for a standalone antivirus with deep features, it’s not the right tool. If you want one subscription that handles VPN and basic antivirus together, the math works out.

What Is Surfshark Antivirus? (It’s Part of Surfshark One)
Surfshark Antivirus isn’t sold as a standalone product. It’s included in Surfshark One, the company’s security bundle that also includes the VPN, Surfshark Alert (data breach monitoring), and Surfshark Search (a private search engine). The bundle costs $3.39/month on a 2-year plan — compared to $2.49/month for VPN-only. That’s $0.90/month more, or about $21.60 over two years, for the antivirus plus three other tools.
Platform availability matters here: Surfshark Antivirus works on Windows and macOS for desktop, and Android for mobile. iOS is not supported — and given Apple’s sandbox restrictions on iOS, this won’t change. If you need iPhone antivirus coverage, Surfshark One doesn’t deliver that. Every Surfshark antivirus review should mention this upfront.
How We Tested Surfshark Antivirus in 2026
Our test environment: a Windows 11 Pro machine (Intel Core i7, 16 GB RAM) and a MacBook Pro running macOS Sequoia. We ran three types of tests: a static malware detection test using EICAR test files and a set of real-world malware samples from the last 90 days (sourced from MalwareBazaar), a system performance comparison before and after installing Surfshark Antivirus, and a real-time protection test involving drive-by download simulation.
We also cross-referenced against AV-TEST and AV-Comparatives results from their most recent consumer antivirus rounds. Surfshark Antivirus is a relatively new entry and not yet in AV-TEST’s full recurring test rotation — something worth knowing when evaluating it against Norton or Bitdefender, both of which have years of published third-party test data.
Malware Detection: What Our Tests Found
On our Windows test machine, Surfshark Antivirus detected 94 of 100 malware samples from our MalwareBazaar set. The 6 misses were all variants of obfuscated ransomware payloads from the last 30 days — meaning zero-day or near-zero-day threats that many established antivirus tools also miss on first exposure. Against older, known malware, detection was 100% across the board.
EICAR test files (the industry-standard simulated malware) were caught instantly on both Windows and macOS. Real-time protection blocked our drive-by download simulation on Windows correctly. On macOS, detection was slower — about 4 seconds from file write to quarantine, compared to 1–2 seconds on Windows. Not a dealbreaker for most users, but relevant if you’re specifically evaluating it for Mac endpoint security.
The surfshark antivirus review comparison point: Bitdefender and Norton typically detect 99–100% of samples in AV-TEST’s comprehensive rounds, which include more edge cases than our test. Surfshark’s 94% against recent samples is decent for an entry-level antivirus bundled with a VPN. It’s not best-in-class detection. It’s good enough for most users who are at low-to-medium risk.
System Performance: How Much Does It Slow You Down?
This is where Surfshark Antivirus performs well. We measured boot time, application launch times (Chrome, VS Code, Adobe Lightroom), and CPU usage during a full system scan. Results on the Windows i7 machine:
| Metric | Without AV | With Surfshark AV | Change |
|---|---|---|---|
| Boot time | 18.2s | 19.1s | +0.9s |
| Chrome launch | 1.4s | 1.6s | +0.2s |
| CPU (idle) | 2% | 3–4% | +1-2% |
| CPU (full scan) | — | 22–35% | — |
| Full scan duration | — | 14 minutes | — |
The numbers are solid. A 0.9-second boot increase and 1–2% extra CPU at idle are essentially invisible in daily use. The full scan hits 35% CPU at peak, but that’s comparable to Malwarebytes and lower than Norton during deep scans. Surfshark Antivirus uses a cloud-based approach to keep the local footprint small — the client app is 60 MB installed, versus 300+ MB for Norton 360.
Features: What Surfshark Antivirus Actually Includes
Real-time protection: A common surfshark antivirus review question is whether real-time protection can be trusted. It is on by default, monitors file writes, downloads, and process launches for malicious behavior. Worked correctly in our tests, with no false positives on legitimate software during 8 weeks of use.
Scheduled scans: You can schedule daily, weekly, or custom scans. The interface is clean and works without issues. Quick scan covers active processes and common malware locations; full scan covers the entire drive.
Webcam protection (Windows only): Blocks unauthorized apps from accessing your webcam and notifies you when any application requests camera access. Useful feature, correctly blocked our test process from accessing the webcam without user permission.
Anti-phishing: Integrates with the VPN layer to block known phishing domains at the DNS level. This is shared with Surfshark’s CleanWeb feature — the antivirus itself doesn’t add browser extension-level phishing detection that tools like Bitdefender provide. If you’re a heavy browser user who clicks links frequently, a dedicated browser security extension adds coverage this tool doesn’t.
What’s missing: No password manager, no parental controls, no identity theft insurance, no dark web monitoring beyond what Surfshark Alert provides separately in the bundle. These features appear in Norton 360 Deluxe and Bitdefender Total Security. For users who want a full security suite, Surfshark Antivirus as part of Surfshark One is not comparable to those packages.
Surfshark One Pricing: Is the Bundle Worth the Extra Cost?
The pricing argument for Surfshark One is simple. If you already pay for Surfshark VPN (Starter plan at $2.49/month), upgrading to Surfshark One costs $0.90/month more. For that $0.90, you get antivirus protection, data breach monitoring via Surfshark Alert, and a private search engine. That’s a reasonable value add.
If you’re starting from zero and comparing Surfshark One at $3.39/month to alternatives: Norton 360 Standard is around $4–5/month after the first year. Bitdefender Total Security is around $3–4/month. For comparable money, those products offer better antivirus depth and more established third-party testing. The Surfshark One advantage is the VPN included — Norton’s bundled VPN is significantly weaker than Surfshark’s core VPN product.
The best use case for Surfshark One: you already use or want Surfshark VPN, and you want basic antivirus protection included without paying for a separate subscription. It’s an upgrade to your existing VPN subscription, not a replacement for a serious antivirus product.
Who Should Use Surfshark Antivirus — and Who Shouldn’t
Surfshark Antivirus makes sense for: existing Surfshark users who want to add antivirus coverage without a second subscription, Windows and Android users with moderate threat exposure (home users, casual browsing), and anyone who prioritizes low system impact over maximum detection rates.
Surfshark Antivirus is not the right choice for: iOS users (not supported), small businesses needing centralized endpoint management, users in high-risk environments who need consistently 99%+ detection rates with published third-party audit data, and macOS users who want fast, macOS-native security with deep system integration.
The honest surfshark antivirus review verdict: it’s a solid bundled tool, not a best-in-class standalone antivirus. Every surfshark antivirus review needs to be clear on this distinction. If the comparison is “Surfshark One bundle vs. separate VPN + separate antivirus,” the bundle wins on price and simplicity. If the comparison is “Surfshark Antivirus vs. Bitdefender as your primary security tool,” Bitdefender wins on features and testing depth. These aren’t the same question.
Surfshark Antivirus Review: Frequently Asked Questions
Does Surfshark Antivirus work on iPhone?
No. Surfshark Antivirus is available on Windows, macOS, and Android only. Apple’s iOS sandbox architecture prevents third-party apps from scanning other apps or system files, which is why no legitimate antivirus product can offer real-time scanning on iPhone. iOS security comes from the OS itself. If you need iPhone security tools, look at security apps that cover phishing protection and VPN — the Surfshark VPN itself works on iOS and provides those layers.
Is Surfshark Antivirus included in the basic Surfshark plan?
No. The antivirus is only available with the Surfshark One bundle, which costs $0.90/month more than the Starter VPN plan on a 2-year subscription. The base Surfshark Starter plan includes VPN, CleanWeb ad-blocker, and MultiHop — but not antivirus. You need to be on the One or One+ tier to access it.
Has Surfshark Antivirus been independently tested by AV-TEST or AV-Comparatives?
As of mid-2026, Surfshark Antivirus has not completed a full recurring test cycle with AV-TEST or AV-Comparatives the way established vendors like Bitdefender, Norton, and Kaspersky have. This is a meaningful gap — independent lab testing over multiple months is how antivirus products prove their detection rates under real-world conditions. Surfshark’s VPN has been audited by Deloitte, but the antivirus component lacks equivalent third-party verification. This doesn’t mean it’s unsafe — our own tests showed solid basic detection — but users who need verified numbers should factor this in.
Can Surfshark Antivirus run alongside Windows Defender?
Yes, but with caveats. Windows Defender typically disables itself when another antivirus is detected to avoid conflicts. Surfshark Antivirus registers as your primary Windows Security provider, so Defender runs in limited mode alongside it. This is standard behavior across third-party antivirus products. You don’t lose Windows Defender entirely — its firewall and browser protection remain active — but the real-time scanning role passes to Surfshark Antivirus.
Surfshark Antivirus vs. the Competition: Where It Stands
Putting surfshark antivirus review numbers next to established tools shows the tradeoffs clearly. This surfshark antivirus review comparison uses our own test data, not vendor claims. Bitdefender Total Security costs around $3–4/month, consistently earns AV-TEST top scores, includes a password manager and parental controls, and has ten years of published independent test data. Norton 360 Standard adds identity theft insurance and a VPN — though Norton’s VPN is widely considered inferior to Surfshark’s own VPN product. Malwarebytes Premium is $4/month and specializes in malware remediation rather than prevention.
Surfshark Antivirus doesn’t try to compete on feature depth. Its real competition is “Surfshark VPN + no antivirus” — and against that baseline, upgrading to Surfshark One for $0.90/month more is a straightforward decision. You get real-time protection, scheduled scans, and webcam protection for less than a cup of coffee per month added to your existing subscription.
The comparison that doesn’t favor Surfshark: if you’re already using Bitdefender or Malwarebytes as your primary antivirus, there’s no reason to switch to Surfshark Antivirus unless you also want to consolidate your VPN subscription. The detection depth isn’t better, and you’d be giving up years of published performance data for a tool that’s still establishing its testing track record.
Testing Surfshark Antivirus on macOS Specifically
The macOS portion of our surfshark antivirus review deserves its own section because the experience differs meaningfully from Windows. On our MacBook Pro running Sequoia, Surfshark Antivirus installed without issues and the interface matched the Windows version closely. Scan speeds were comparable — a full scan of a 512 GB drive completed in about 18 minutes.
Detection on macOS worked against our known-malware set, including macOS-specific samples like Shlayer variants and AdLoad adware families. All known samples were caught. Where macOS performance lagged was on newly discovered samples: our drive-by download simulation produced a 4–6 second detection lag compared to 1–2 seconds on Windows. For macOS users, that window matters more than it might on Windows, because macOS-targeted malware has increased significantly since 2022 as Mac market share has grown.
One macOS-specific note: Surfshark Antivirus requires Full Disk Access permission on macOS to scan system directories. This is standard for any antivirus on macOS — but users who prefer to limit app permissions should know upfront that granting Full Disk Access is required for complete protection. Without it, the antivirus can’t scan outside your home directory.
For Mac users specifically, we’d also point to our best antivirus reviews roundup where we compare macOS-specific performance across Bitdefender, Norton, and Malwarebytes. Surfshark Antivirus is a capable entry for light-to-moderate Mac users, but dedicated Mac-focused options like Malwarebytes for Mac have deeper macOS integration and a longer track record on Apple platforms.
Conclusion: Is Surfshark Antivirus Worth It?
Our surfshark antivirus review conclusion: it delivers what it promises for the price. To answer the core surfshark antivirus review question directly — yes, Surfshark antivirus is worth the $0.90/month premium over the base VPN plan. At $0.90/month extra over the base Surfshark VPN plan, it’s real-time malware protection with acceptable detection rates and minimal system impact. The 94% detection rate on recent samples is not best-in-class, but it covers the vast majority of real-world threats that home users face. The performance overhead is among the lowest we’ve measured for any antivirus in this category.
The limitations are real: no iOS support, no AV-TEST track record yet, and a feature set that doesn’t match premium standalone antivirus suites. If you need something you can point to a CISO and say “AV-TEST certified, top-rated since 2019,” this isn’t it. But for home users who already use Surfshark VPN, it’s the sensible upgrade. It means one subscription handles both your VPN and your antivirus, which is genuinely convenient and genuinely cost-effective.
If you’re starting from scratch and evaluating antivirus-only tools, see our best antivirus roundup for the full picture. If you’re already on Surfshark and want to know whether upgrading to Surfshark One makes sense — yes, it does. The antivirus alone justifies the small price difference.
