Wormguard defends against email worms that can cause billions of dollars in damage as they spread like wildfire across the planet. It will also catch many other malicious programs and stop them, and it cannot be terminated like other programs. Wormguard analyses files generically using heuristic and intelligent rule-sets rather than relying on signatures for known worms. Detected NIMDA BadtransII/Badtrans.b@mm generically.
