The Austria based security solution company, Emsi Software, has just released the latest version of its free antivirus application, a-squared Free 4.0, for non-commercial or home users. This free antivirus tool utilizes two separate scanning engines – the a-squared Anti-Spyware and the Ikarus Anti-virus engine to perform a comprehensive scanning and checking for malicious software (Malware) including Trojan Horses, Worms, Spyware, Adware, Backdoors, Keyloggers, Bots, Dialers, etc.

The a-squared Free 4.0 can be downloaded via the link here. This antivirus application works well with Windows XP, Windows Vista as well as Windows Server 2003/2008.

Comparatively, the popularity of a-squared Free definitely cannot match popular antivirus applications such as AVG Anti-Virus, Norton AntiVirus, Avast Home, Avira AntiVir Personal, McAfee, etc. However, in terms of features and capability, a-squared Free is considered on par with other free antivirus software. Users who are looking for a free antivirus application to install into their system or to utilize it as a second scanner for double protection could give this a try.

Update: a-squared Free 4.5
