Top-of-the-line protection for those who want it all.


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.
NEW 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.
You lock your front door to keep thieves out of your home, so why should your computer be any different? Firewall keeps you safe from all kinds of intruders.
Sandbox 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.
Passwords Too many passwords, none of which are safe? It's fairly common. Remember just one, and Avast Passwords will take care of the rest.
NEW 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.
Automatic Software Updater The Internet is full of extensive guides on how to exploit security issues in outdated software. The key is to be faster than hackers. Automatically.
Data Shredder Do you share your PC, have it repaired, or are about to sell it? It's easy to recover deleted files that are for your eyes only. Wipe them for good.
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.
Anti-spam Spam isn't just annoying. It can be dangerous, too. Internet Security keeps you, and your money, safe from threats like phishing emails. The anti-spam is available as a separate, free download.
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.
