Cinderella.360
These are not dangerous memory resident parasitic viruses. They copy themselves into the Interrupt Vectors Table, hooks INT 16h, 21h and write themselves to the end of .COM-files that are executed or opened. After some INT 16h calls they create zero-length file:
"Cinderella.360.a": CINDEREL.LA file
"Cinderella.360.b": CINDYRUL.EZ file
These viruses contain the internal strings:
"Cinderella.360.a": cInDeReL.la
"Cinderella.360.b": CindyRul.ez
Cinderella.779
It's a memory resident very dangerous virus. It hooks INT 21h and writes itself into the beginning of the COM-files and the end of the EXE-files upon their opening or execution. It erases the disk C: FAT and types "Cinderella II".
