Back in the 50s, a group of researchers were experimenting with a bit of code on a supposedly isolated machine at a university. The code was successful, reproducing in the machine's resources and packing up the highspeed tape drive's storage volume. Somehow a floppy with the code got into the university network and shut that down too. This was the first virus, an UNINTENTIONAL distribution.
If you want to play with malware, first learn English (or at least one of the other human languages) well enough that you don't have everyone thinking you're illiterate. Then research it, and get a computer theory college education, and get a job at Network Associates or Symantec. Otherwise you will have the previously mentioned FBI, the CIA, the FCC, and every cop in your home state or country after you thinking you're Mike Resnick's brother.
