Notifications from virus scanners is backscatter, just the same as the 
backscatter generated by Smurf attacks. The virus scanners are contributory 
technology in the conduct of a denial of service attack in exactly the same 
way as having directed broadcasts enabled on your routers was (read RFC 
2644 for the details).

Please let's stop building technology that aids in the conduct of DoS
attacks.
