Security firm AVG is setting a trend in threat detection as it introduces a new anti-virus software that uses behaviour-based approach in identifying new viruses.

This new application called the AVG Identity Protection has been designed to be pro-active as it watches out for suspicious behaviours of unidentified programs and analyses its characteristics prior to entry. Once malware is suspected to be carried by the program, the software then locks the system secure by shutting down activity.

The web-browsing software Firefox from Mozilla is now free from holes as its makers issued security advisory 2009-10 Tuesday to patch several memory safety hazards.

Pehrson reported that the memory safety hazards in Portable Network Graphics (PNG) libraries in Mozilla to render images could be used by a malicious website and execute arbitrary codes.
