In reply to your request for virus code, I’ll tell you I’ve never written a virus, nor do have I ever had any desire to do so. I have no interest in writing code that causes harm to other people’s property. Having said that, viruses do contain some really interesting code, so if you really want to study them you can find virus code simply by going to Google and typing in “example virus code.” This should provide you with links to C, Assembly, and VBS code for some of history’s most popular computer viruses.

But if you can’t figure how to find example code on the Internet, I’m fairly confidant that you won’t be able to decipher the code if I point you in the right direction
