Anti virus software that doesnt need updating

A new anti-virus software Rudra doesnt need updating.. coz it uses advanced form of heuristics-centric protection, that's proactive form of intelligent threat scanning that seeks to understand the behavior and patterns of viruses in order to thwart unknown threats.

Local S'pore startup Rudra Technologies developed it, and retails it at S$75 for single licence; works for Windows 2000 and XP.
