Pros and cons

AdBlocker Ultimate

Pros

  • Wide coverage across Windows, macOS and Android for desktop, mobile and browser use
  • DNS privacy options include doh, dot and dnscrypt on supported Android builds
  • Focused ad blocking scope via ad blocker that keeps setup clear

Cons

  • Closed review path, as open source is no, which limits outside code checks
  • Support runs on email and help centre only, which limits direct contact routes

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

AdBlocker Ultimate

Who it suits

  • Everyday browser readers who want free blocking before paying for wider cover
  • Multi browser households that want the same ad blocker across desktop and mobile

Who should look elsewhere

  • Choose DeleteMe for data broker removal rather than browser ad blocking
  • Choose addy.io for masked mail handling rather than page level ad blocking

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

AdBlocker Ultimate

Does AdBlocker Ultimate have a free plan+

Yes. The model is listed as free, so browser blocking starts without charge. Paid app cover is separate for system wide blocking, so check which placement matches the devices used for daily browsing.

What are the limits of the free version+

Limits are described as Free browser extension; paid app for system-wide blocking. That means browser extension use is free, while full system wide blocking sits in the paid app. Readers who only need browser cover can stay free, while wider cover needs the paid tier.

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.
