Free Antivirus Download - Avast!

State of the art antivirus and antispyware scanning engines make Avast! Anti-Virus a top competitor in detecting malicious software.

“On access” technology unique to Avast! Anti-Virus is able to check each time kernel modules are loaded and warns you.  This allows even unknown rootkits to be detected and stopped.

Thanks to the huge userbase of Avast! Anti-Virus, many virus samples are collected and analyzed automatically.  Avast! also employs dozens of malware analysts to further process the vast information network.

Suspicious executable files are able to be ran in a protected environment using code emulation which provides a heuristic to determine the properties of different malware.

The latest version of Avast! includes the ability to analyze heuristically both executable files as well as script malware.

Avast! now detects potentially unwanted programs such as adware, commercial remote administrating software, and others.  Custom rules can be set up to configure the detection of these programs.
