Avast Premium Security

The full protection suite with the firewall, ransomware shield, sandbox, and web filtering all switched on, running at the paid tier without the upgrade prompts.

Version 26.7.11086 412 MB Windows 10 / 11 (64-bit) Updated 3 days ago

Overview

What this release is

The premium tier is where the components that actually matter live. The free version covers file and behaviour scanning, but the firewall, the ransomware shield with protected folders, the sandbox, and the network inspector are all paid features, and this build enables the full set from the first launch.

The ransomware shield is the component most worth having. It watches a defined list of folders and blocks any process that has not been explicitly approved from modifying files inside them, which stops the encryption pass before it gets past the first few documents rather than reporting it afterwards.

The sandbox is the second reason people move up a tier. Any executable can be launched in an isolated container where it can write, install, and register whatever it wants without touching the real system, and the container is discarded on close. For examining an unknown file it is far safer than the alternative.

The interface has been cleaned up considerably over the last few releases. Scans run quietly, the notification stream is far less intrusive than it used to be, and the upgrade banners that dominated the free version are absent at this tier.

Feature set

What you get

Ransomware shield

Protected folders that only approved processes can write to, blocking an encryption pass at the first file.

Sandbox

Run an unknown executable inside an isolated container that is discarded when it closes.

Firewall

Per application network rules with profiles that switch automatically between trusted and public networks.

Web filtering

Blocks known malicious hosts and phishing pages at the connection level rather than in the browser.

Network inspector

Scans the local network for exposed devices, default passwords, and open ports.

Quiet operation

Scans schedule themselves around idle time and the notification stream stays out of the way.

Changes in this build

What changed

Rebuilt scan engine with a noticeably smaller memory footprint
Ransomware shield now covers network mapped folders
Firewall rule editor reworked to be readable rather than technical
Web filtering updated with a faster local reputation cache
Fixed the compatibility issue with recent Windows feature updates

Installation

How to install it

Remove any other security suite first. Two real time scanners on one machine will fight each other.
Extract the archive to a short path and run setup as administrator.
Choose the custom installation and deselect the browser extension if you do not want it.
Apply the included licensing step before the first restart.
Open the interface and confirm the premium components show as active rather than as upgrades.

Questions

Before you start

Can it run alongside the built in Windows protection?

The built in scanner steps aside automatically once this is registered as the active provider.

Do virus definitions still update?

Yes. Definition updates run normally and do not affect the tier state.

Why does the tier revert after a program update?

A major version update replaces the licensing components. Reapply the included step after updating.

Is the browser extension required?

No. Web filtering works at the connection level with or without it.
