Avast Free Antivirus

Avast Free Antivirus for Windows

Avast Free Antivirus helps protect a PC from viruses, spyware, phishing, and other threats. Its interface centers on protection status, Smart Scan, and individual security components, making common checks easy to reach.

Features

• real-time scanning of files as they are opened or changed;
• behavior monitoring for running processes;
• Smart Scan for a broad system check;
• full, targeted, boot-time, and custom scans;
• quarantine for isolating detected objects;
• automatic application and virus-definition updates.

Installation uses Avast’s official online installer. An internet connection is required to fetch components and keep definitions current. Some protection modules may require a Windows restart after installation.

Note: running two real-time antivirus products at the same time is not recommended because it can cause conflicts and reduce performance.
