6 layers of antivirus security.
Sometimes your operating system’s built-in protection isn’t enough. Adding Avast Free Antivirus lets you run automatic smart scans on software, files, and apps to find cracks where malware can slip in, plus send suspicious files for analysis in the cloud, get threat alerts, and more.
Smart Scan
Scans your device for hard-to-find vulnerabilities in hidden places.
Cyber Capture
Automatically sends suspicious files for analysis in the Cloud, then pushes a cure to Avast users if needed.
Behavior Shield
Alerts you immediately if any of your apps start behaving suspiciously.
File Shield
Alerts you to any suspicious files — before you open them.
Rescue Disk
Scans your device while your system’s switched off, so you can safely remove malware.
Quarantine
Stores potentially harmful files and completely isolates them from the rest of your operating system.
