Crocodiles.1592

Description Crocodiles.1592

It is a very dangerous memory resident parasitic virus. While executing an infected program the virus searches for the COMSPEC string, and infects the command interpreter (COMMAND.COM). While executing an infected command interpreter the virus hooks INT 21h and then writes itself to the end of COM and EXE files (except SCAN.EXE) that are executed.
Depending on its generation the virus also hooks INT 8 (timer) and manifests itself with some sound effect. The virus also calls some other effects and erases the disk sectors, but that code is corrupted, and the computer halts. The virus contains the text string:
CROCODILES

It's a not memory resident not dangerous virus. It searches for a COM- and EXE-files and infects them. EXE-files are infected by a standard way, the COM-files infected into the beginning. This virus contains the encrypted string: "*.com *.exe Only God knows!". Sometimes it decrypts and types:
There was a crooked man, and he went a crooked mile,
He found a crooked sixpence against a crooked stile,
He bought a crooked cat, which caught a crooked mouse,
And they all lived together in a little crooked house.
