This Surfshark antivirus review covers what matters most before you decide: detection track record, 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.
The short version: Surfshark Antivirus detects malware reliably, 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 typically costs a modest premium per month over the VPN-only plan — check Surfshark’s current pricing page for exact figures, since promotions change.
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.
What This Review Covers
This review draws on Surfshark’s own published documentation on its antivirus engine, and a comparison against established, independently tested products like Bitdefender and Norton. Surfshark Antivirus is a relatively new entry to the market and is not yet part of AV-TEST‘s or AV-Comparatives‘ 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: Where Surfshark Stands
Surfshark Antivirus handles known, catalogued malware reliably — standard EICAR test files and common malware families are caught consistently on both Windows and macOS. Where any antivirus engine’s detection typically gets tougher is against very recent, obfuscated, or novel payloads, and this is an area where established vendors with years of signature and behavioral-detection tuning (Bitdefender, Norton, Kaspersky) tend to have an edge, reflected in their consistent top scores across many AV-TEST and AV-Comparatives cycles.
The honest comparison point: Bitdefender and Norton typically post detection rates in the high 90s to 100% in AV-TEST’s thorough rounds, which include a wide range of edge cases collected over years of testing. Surfshark’s antivirus engine is capable for an entry-level tool bundled with a VPN, but it doesn’t yet have the same multi-year independent track record. It’s a reasonable choice for most users at low-to-medium risk; it’s not the pick for someone who specifically needs the highest independently verified detection numbers.
System Performance
This is where Surfshark Antivirus performs well. It uses a largely cloud-based detection approach, which keeps the local client small (well under 100 MB installed, versus several hundred MB for some full security suites) and limits impact on boot time and everyday application launches to something most users won’t notice.
CPU usage during a full scan is naturally higher than idle, as with any antivirus, but comparable to lighter tools like Malwarebytes and generally lower than heavier full suites during deep scans. For most home users, the day-to-day performance impact is close to invisible.
Features: What Surfshark Antivirus Actually Includes
Real-time protection: On by default, it monitors file writes, downloads, and process launches for malicious behavior. In regular use, it runs quietly without generating a stream of false positives on legitimate software.
Scheduled scans: You can schedule daily, weekly, or custom scans. The interface is clean and straightforward. 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.
Anti-phishing: Integrates with the VPN layer to block known phishing domains at the DNS level, shared with Surfshark’s CleanWeb feature — the antivirus itself doesn’t add browser extension-level phishing detection the way tools like Bitdefender do. 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, upgrading to Surfshark One typically costs a small premium per month. For that, you get antivirus protection, data breach monitoring via Surfshark Alert, and a private search engine — a reasonable value add. Always check Surfshark’s current pricing page for exact current rates, since plans and promotions change.
If you’re starting from zero and comparing Surfshark One to alternatives: Norton 360 Standard and Bitdefender Total Security are both broadly in a similar monthly price range after the first year. For comparable money, those products offer more established third-party testing and deeper feature sets. The Surfshark One advantage is the VPN included — Norton’s bundled VPN is generally considered 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 dedicated, deeply-featured 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.
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 extensively independently verified detection track records, and macOS users who specifically want the deepest macOS-native security integration available.
The honest verdict: it’s a solid bundled tool, not a best-in-class standalone antivirus. 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 independent 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 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 a small amount more per month than the Starter VPN plan. 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 this review, 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 undergone independent audit, but the antivirus component lacks equivalent third-party verification. This doesn’t mean it’s unsafe, but users who need verified numbers should factor this in.
Can Surfshark Antivirus run alongside Windows Defender?
Yes, but with caveats. Windows Defender typically switches to limited mode when another antivirus is detected to avoid conflicts. Surfshark Antivirus registers as your primary Windows Security provider, so Defender runs alongside it in that reduced role. 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 next to established tools shows the tradeoffs clearly. Bitdefender Total Security consistently earns AV-TEST top scores, includes a password manager and parental controls, and has 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 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 a small monthly premium is a straightforward decision. You get real-time protection, scheduled scans, and webcam protection for not much more than 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 strong reason to switch to Surfshark Antivirus unless you also want to consolidate your VPN subscription. The detection depth isn’t clearly better, and you’d be giving up years of published performance data for a tool that’s still establishing its independent testing track record.
Surfshark Antivirus on macOS
The macOS version of Surfshark Antivirus deserves its own mention because the experience differs somewhat from Windows. The macOS app mirrors the Windows interface closely and installs without complications, with scan speeds broadly comparable for similarly sized drives.
Detection against known Mac-specific malware families (Shlayer variants, AdLoad adware, and similar) is solid on macOS. As with most antivirus engines, response to newly discovered samples can lag slightly behind response to well-established, catalogued threats — a pattern that’s true industry-wide, not unique to Surfshark. For macOS users, that gap matters somewhat more than it might on Windows, since macOS-targeted malware has grown meaningfully as Mac market share has increased.
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 conclusion: it delivers what it promises for the price. If you’re already paying for Surfshark VPN, the antivirus upgrade is worth the small monthly premium — you get real-time malware protection with reasonable detection and minimal system impact. It’s not best-in-class detection, but it covers the vast majority of real-world threats that home users face, and the performance overhead is among the lightest we’ve seen for any antivirus in this category.
The limitations are real: no iOS support, no established independent lab track record yet, and a feature set that doesn’t match premium standalone antivirus suites. If you need a product with a long, independently verified detection history to point to, this isn’t it yet. But for home users who already use Surfshark VPN, it’s a sensible upgrade — one subscription handles both your VPN and your antivirus, which is genuinely convenient and cost-effective.
