Technical Details

Sandrine took advantage of the fact that the DOS EXEC loader executes a COM file before executing a similarly named EXE file if both files are found in the same directory. Sandrine virus has an activation routine, during which it creates a file called SANDRINE.COM. This file contains the text:

Sandrine Baillieux thoughts of you are in my mind         (c) 1994 by BrokenHeart
