Intelligent antivirus

Detects all kinds of nasty threats, from viruses to malware. Yes, even spyware, ransomware, and phishing attacks.


Personal, real-time threat detection. Sends unknown files to the Avast Threat Labs to be analyzed by our experts, and quarantines them if they’re dangerous.

Behavior Shield

Malware loves to act innocent. Avast analyzes app behavior in real-time to catch any suspicious changes before damage is done.

Smart Scan

A simple click has never been more powerful. Checks your PC and network for all kinds of issues – and tells you how to fix them instantly.


Ever downloaded a file from a shady server and suspected it’s trouble? Test files in a sealed space first, and keep the rest of your PC safe.

Wi-Fi Inspector

Is your router set up properly to block threats? We’ll tell you. Otherwise, anyone can break into your home network and anything connected to it.

Browser Cleanup

Get rid of mystery toolbars, add-ons, and extensions that were installed without you noticing – and without your permission.


Too many passwords, none of which are safe? It’s fairly common. Remember just one, and Avast Passwords will take care of the rest.

Passive Mode

Don’t like to play favorites with antivirus? No problem. Avast can sit quietly in the background until you need our other advanced features.

Real Site

Your router settings can be changed to connect you to a fake site. Why? So hackers can steal your banking details. SecureDNS keeps your online banking safe.

SafeZone Browser

The new way to browse, bank, and shop. With a suite of tools designed to provide extra protection, discover why SafeZone is the world’s most secure browser®.

Game Mode

Automatically puts your Windows and other notifications on hold so you’ve got maximum processing power and speed for your game.
