avast! Free Antivirus Features


Real Time Anti Virus Protection

avast! Free Antivirus features improved Antivirus and anti-spyware engine performance. The scanning engine has been optimized to allow faster scans of EXE files – up to twice as fast - while scans of text contents (such as web pages and documents) are up to 10 times faster.

Real Time Anti-Rootkit Protection

Unique technology checks files and all kernel-mode drivers that the operating system is loading for signs of rootkit behavior. This enables even unknown rootkits to be detected and stopped before they can do any damage.

Automatic Updates

Continuous Streaming Updates - Every day, at least 250 virus-database micro-updates (the size of a simple text message, every 3-5 minutes) give you real-time protection against threats.

Web Shield

avast! scans all visited web pages and checks all files, pages and java scripts downloaded from the internet. Thanks to the Intelligent Stream Scan feature, the Web shield doesn't slow down your computer or web browsing.

Intelligent Scanner

avast! will reduce the number of required file scans by up to 80% through a white list of proven safe applications. The files that have been scanned and identified as safe are not rescanned unless they have been changed.

Behavior Shield

This software will monitor the activity on your computer using a number of sensors and report and block any suspicious behavior it finds.

Browse Securely & Privately

avast! comes with a Do Not Track feature for your browser plugins that identifies tracking software and gives you control over which companies can follow what you do online.

Network Shield

Provides protection against network-based viruses. The module has two main components: a URL blocker, designed to block malicious URLs, and a lightweight intrusion-detection system.
