NTBugtraq Editor's Note:
Most viruses these days use spoofed email addresses. As such, using an
Anti-Virus product which automatically notifies the perceived sender of a
message it believes is infected may well cause more harm than good. Someone who
did not actually send you a virus may receive the notification and scramble
their support staff to find an infection which never existed in the first
place. Suggest such notifications be disabled by whomever is responsible for
your AV, or at least that the idea is considered.
