I apologize for not explaining this better. As mw3demo has pointed out, yes the AV companies DO already have signatures for these viruses. However, I simply worked with the code I could find. These files are more of a proof of concept than anything else. Eventually, I plan to find some newer viruses, or write them myself, and then transform those into vaccines as well. These were simply a "practice run" on the most readily available virus code at the moment. So, actually, the thing that would be the most helpful would be if you could look at the C code file and let me know if I missed anything dangerous.
