most skiddies who write virus use lame programs like "hacktheplanet.exe"(i made that up hehehe) which usually create *.vbs files, however in specific terms most c compilers(Borland, gcc that comes with cygwin, MicroSoft's Visual basic(it is the wierdest language ever just to cite a few)) you might want to also add in your report that most viruses are distributed through web pages, games, and (html) email
