This is a great idea for a intro level course. Not only does it teach about viruses, but about social engineering viruses - the ones that do no harm unless you "buy in" and follow the malicious instructions. Leave a cheap USB stick on their desks, or on the floor. It just needs to contain the self written virus and autorun.ini, those who plug it in fail, those that don't, pass - at least the first stage of the test. Then let them develop their own break-out groups to remove it from those student's machines that fail the first part. Great lesson! Very inventive and engaging! Make the virus like the one (I cannot remember the exact name) that infects machines by displaying a Microsoft Security Essentials message saying IE is infected, then tries to get you to download anti-malware software that actually is malware. My two cents ( of course my 2 cents are valued at rates from the 1970's, so through devaluation and inflation... whatever)
