Virus code 21: datechange

This is a simple code that changes system time . It is written using c/c++ but can be easily converted to java.

Now You need to compile it but not run it i.e just click on compile but not on run option or you will only get infected by the virus.



To set back to the old date you can use before the "return o;" statement

setdate(&old_date);

You might need time.h header file but i am not very sure about it.



Although the code is extremely simple be very careful what you do with this virus as you can go to jail for spreading this.
