To keep you safer online, Avast Free Antivirus also provides you:

Defense against phishing and more
Our AI technology helps you block risky website links in your emails or web browser that you could open by accident. Enhance your security against scams and cyberthreats.
A fast way to boost digital security
It only takes a moment to install Avast Free Antivirus. 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

What’s inside the latest version?

Get a beautifully intuitive interface, advanced application protection, and a new passive mode for running multiple security software programs 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 back up 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.
Your game or movie time is now uninterrupted
We’ve renamed Game Mode and taught it some extra tricks. Now called Do Not Disturb Mode, it blocks distracting pop-ups whether you’re gaming, watching movies, or presenting in full-screen mode.
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
Easy to install, effortless to use
Our antivirus software scans for security and performance issues and helps you to fix them instantly. It also protects you in real time by analyzing unknown files before they reach your desktop PC or laptop — all for free.
