Easy to install,
effortless to use

Avast’s antivirus products scan for security and performance issues and help you fix any issues instantly . They protect you in real time by analyzing unknown files before they get to you.

What’s inside the latest version?

A beautifully intuitive interface, advanced application protection, a new passive mode for running multiple security products in parallel — and a little something for you gamers and movie buffs.

Designed for effortless security

Just a click of our fresh, new, easy-to-use interface checks everything from your passwords to your home network security.

NEW
Game or movie time. Now uninterrupted

We’ve renamed Game Mode and taught it some new tricks. Now called Do Not Disturb Mode, it blocks distracting popups whether you’re gaming, watching movies, or presenting in fullscreen.

Introducing Behavior Shield

We don’t just check your applications for malware. We now keep an eye on their behavior to make sure they don’t suddenly go rogue.

Avast Free Antivirus is no ordinary antivirus

On top of our latest features, our free antivirus covers basic intelligent threat-detection and real-time protection for your PC with such a light touch, you never even know it’s there.

Intelligent Antivirus
Detect and block viruses, malware, spyware, ransomware and phishing. We use smart analytics to stop threats before they affect you.
CyberCapture
Automatically send suspicious files for analysis in the cloud, and push a cure to all Avast users if it's a threat.
Wi-Fi Inspector
Automatically detect weaknesses in your home Wi-Fi and strangers piggybacking on your network.
Smart Scan
Find all those cracks which allow malware to slip in, from unsafe settings and passwords to suspicious add-ons and out-of-date software.

Layer upon layer of security

Avast’s antivirus products use multiple layers of security to keep you safe from even the newest, never-before-seen threats.

The world’s most trusted antivirus

But just don’t take our word for it.

The UI for your software - amazing. Great work over the years. Can't say enough good things!
