[Year 12 SofDev] SD 2011 Post Mortem -Worms

Fri Nov 18 12:59:09 EST 2011

Hi,

All of the options except A requires worms to infect files, so while
whether they are able to do so can be debated, it would not affect the
answer. Worms can travel by email, but they also have other means of
travel, so it cannot be B or C, and I hope no one selected A.

Regards,
Julian
