Get advanced privacy protection beyond antivirus software
To keep you safer online, Avast Free Antivirus also includes:
6 layers of security
Effortlessly run smart scans on software, files, and apps to find vulnerabilities, plus analyze suspicious files in the cloud, get threat alerts, and more.
Easy to install and use
It only takes a moment to install Avast Free Antivirus and once it’s done, it’ll run quietly in the background, protecting you against viruses and other malware in real time, 24/7.
Wi-Fi network security
Connect safely to any Wi-Fi network, even unsecured public networks, plus see who’s using your home Wi-Fi and block any intruders with a click.
Protection against ransomware attacks
Protect your information. Don't let your personal photos, files, and documents fall victim to hackers using ransomware.
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.
Avoid becoming the victim of digital extortion
Ransomware is quickly becoming one of the most common — and dangerous — types of malware out there. Avast Free Antivirus protects your devices against havoc-wreaking ransomware so you don’t become the victim of digital extortion.
Why cloud backup may not be enough to save you
It's always a good habit to backup your files in the cloud in case disaster strikes and you become a victim of a ransomware attack. The problem is that the ransomware-encrypted version of your files is immediately synced with the cloud too, so unless your backup solution also stores historical versions of your files, you're in trouble.

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

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.
Easy to install, effortless to use
Avast’s antivirus scans for security and performance issues and helps you to fix them instantly. It also protects you in real time by analyzing unknown files long before they reach your device. And it’s free — so give it a try.
