Surfshark One (Antivirus)

Pros and cons
Avast
Pros
- The free version is not a trial: it includes Free Cleanup, Free BreachGuard and a 60 SecureLine VPN trial.
- Premium Security covers 1 to 10 devices on Windows, macOS and Android, so a single licence handles a mixed household.
- SecureLine VPN spans 74 server countries over OpenVPN and IPsec, with a kill switch, split tunnelling and multi hop on top.
Cons
- Renewal is the sting: $77.99 to $99.99 once the first term ends.
- The paid plan spans 1 to 10 devices while the typical free antivirus listed spans 10, so paying buys features rather than device count.
- Support runs on help centre, community and phone only.
Surfshark One (Antivirus)
Pros
- Extras include a VPN, so protection and privacy arrive on one subscription (vpn)
- Covers 5 devices on Windows, macOS and Android
- A trial of 7 days lets you test the paid tier first
Cons
- No free version, so a subscription is the only way to run the protection
- Support runs on email, chat and help centre, with no phone line among them
- 5 devices sits under the group median of 7
Who each suits
Avast
Who it suits
- Budget-first households that want a permanent free baseline rather than a countdown, with Premium Security as the upgrade.
- People who stream and travel, since SecureLine is listed for no-logs, streaming and travel and reaches 74 server countries.
- Buyers weighing a long commitment: SecureLine sells monthly at $4.99 or on a long-term plan at $3.99 with a 30 day refund window.
Who should look elsewhere
- Apple Inc., whose built-in protection covers iOS, iPadOS and macOS and suits readers already inside that ecosystem.
- Comodo (Xcitium), whose free plan reaches 50 and fits teams needing raw endpoint count.
- ESET Brasil, whose first-year price of BRL 64.22 is quoted in reais for readers buying in Brazil.
Surfshark One (Antivirus)
Who it suits
- Readers who already pay for a VPN and want malware protection on the same bill
- Households that fit within 5 covered devices
- People who want one subscription across security tools rather than several separate buys
Who should look elsewhere
- Apple Inc. users, who get security features across iOS, iPadOS and macOS from the operating system itself
- Comodo (Xcitium) users who need room for 50 devices on a single plan
- ESET Brasil readers after a different first-year quote, since its first-year price is BRL 64.22

Questions about each
Avast
How much does Avast cost in the first year?+
Premium Security sells at $49.99 to $69.99 for the introductory year, and Avast also lists an entry point of €3.33 in its store. The first-year figure is a launch price rather than the ongoing rate, so budget for what follows it. Avast ranks 13 of 36 brands on first-year price.
What does Avast charge when the subscription renews?+
Renewal lands higher than the introductory year: $77.99 to $99.99 against a first year of $49.99 to $69.99. Across the brands listed, Avast sits 7 of 22 on renewal price, a stronger position than its entry rank. Anyone staying past the first term should compare renewal, not the launch discount.
Surfshark One (Antivirus)
What does Surfshark One cost at the start and after renewal?+
The first-year price is €75.33, and the monthly option is listed at €2.49. Set the opening figure against the group median of €49.95. What a renewal costs depends on the checkout terms, so the total shown at the point of payment is the figure to check.
Does the plan include a VPN or is that bought separately?+
A VPN is bundled into the same plan and listed among the extras, so antivirus and privacy cover arrive on one subscription rather than two. That bundling is what separates this offer from antivirus sold on its own. Around 97.1% of the products in this group also bundle a VPN.
