Simple Virus For Teaching?

ed1023 writes "Currently I am teaching a 101 class on computers. It is more of a 'demystifying the black box' type of class. The current topic is computer viruses; I am looking for a virus with which I can infect the lab computers (only connected to local network, no outside network connection) that would be easy for the students to remove by hand. Can the Slashdot community point me in any directions? Is there an executable out there that would work, or do I try to write one myself, or is there one that is written that I can compile myself?"

Thanks, dude. My virus scanner just started complaining about my browser cache.

Windows IT guys can be clueless. In a previous job, IT insisted on shutting down my machine and take it away for cleaning because I saved the EICAR test string in cygwin so I could test my Unix boxes' clamav with it. There was no convincing them that the string "X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*" wasn't a virus.
Not even my creds as the author of the world's first heuristic AV scanner, nor my certifications were believed, because Symantec Antivirus claimed it was a virus, so it had to be.

That ITs internal HP printers LCD panels suddenly started displaying "INSERT COIN" had nothing to do with this, I swear.

Not computer related, but similar.

A friend of mine carried a pager years ago. I wrote a script to send a message to his pager every morning at 3am, saying "Low Battery".
