Avast vs Moonlock (2026): which should you pick?

Pick Avast if

• Fits if you want real-time antivirus on a Windows PC and don't want to pay
• Works for families mixing Windows, Mac and phones, up to 10 devices

Look elsewhere if

• Skip it if you want one price for everything, as the VPN and Cleanup are separate subscriptions
• Not for you if auto-renewal bothers you, as paid plans renew by themselves and some trials want a card
• Pricey if you keep it past year one: 10 devices go from $69.48 to $99.99, and one computer from $49.08 to $77.99
• Watch out: first-year prices are for new customers only, and Ultimate renews at $109.99 for one computer
• Tight if you want Bank Mode, Email Guard or webcam blocking free, as they're Premium only; there's no web app

Pick Moonlock if

• Fits if you have one Mac and want a scanner built only for macOS
• Works for a household of 1, 2 or 5 Macs that wants a one-time purchase option

Look elsewhere if

• Skip it if you also use Windows, iPhone or Android, as there is no app for them
• Watch out: the 7-day trial charges $54 on its own when it ends unless you cancel
• Pricey if you pay monthly, at $13.50 against $54 for the year
• Watch out: the one-time $150 may not include major upgrades and new features, and 2- and 5-Mac prices only show at checkout

Avast

• First-year prices are for new customers; from the second year Premium Security is $77.99 for one computer or $99.99 for 10 devices.
• Premium Security does not include the VPN or Cleanup Premium; each needs its own subscription unless you buy Avast Ultimate.
• Premium Security is sold for one device or as Multi-Device for up to 10 across Windows, Mac, Android and iOS.
• Paid subscriptions renew automatically, and some trials ask for a payment method before they start.

Moonlock

• The 7-day trial starts on a yearly plan and charges $54 automatically when it ends unless cancelled.
• Prices for the 2- and 5-device options were not shown without selecting them, so only the 1-device prices are listed here.
• The one-time purchase may not include major upgrades and new features, according to the checkout page.

Avast

Core Shields

File, Behavior and Web shields scan files, watch running programs and block harmful sites in real time, on the free version as well as the paid one.

Ransomware Shield and firewall

The free antivirus includes a Ransomware Shield, a firewall, Network Inspector for home network checks, and Hack Alerts when your logins leak online.

Bank Mode and Real Site

Premium Security opens banking and payment sites in an isolated virtual desktop and guards against DNS hijacking that swaps a real site for a fake one.

Email Guard and Deepfake Guard

Premium Security scans web-based email for phishing and uses AI to flag synthetic voices and videos used in scams.

Sandbox and webcam protection

Premium Security can run suspicious programs in a sandbox, blocks apps from using the webcam, and shreds files beyond recovery.

Avast Ultimate bundle

Ultimate unlocks Premium Security together with Avast VPN, Cleanup Premium and AntiTrack. Bought alone, the VPN and Cleanup need their own subscriptions.

Moonlock

Real-time protection

Scans in the background, even when the app is closed, and checks files, apps and Mail attachments. It neutralizes a risky file but leaves the decision to remove it to you.

Malware scanner

A manual scan of the Mac that quarantines detected malware, and explains what it found, why it is dangerous and what to do next.

VPN and network inspector

A VPN encrypts the connection on untrusted networks, and the network inspector can cut connections to countries the user chooses.

Scam Detector

Paste a suspicious message and the AI-powered detector says whether it looks like a scam.

System protection and Security Advisor

Checks the Mac's security settings and walks through the ones to tighten, plus short advice on safer habits.
