It is a very dangerous memory resident parasitic virus. It hooks INT 21h and when files are created or executed, it searches for .COM and .EXE files and writes itself to the end of file. The virus has bugs and corrupts some files while infecting them. While infecting the virus also deletes the anti-virus data files CHKLIST.CPS and CHKLIST.MS.
On December 2nd it erases hard drive sectors, decrypts and displays the message:
25 WAYS TO PREVENT A VIRUS ATTACKall.
No.2 ALWAYS USE CONDOMS !!
No.25 SELL YOUR COMPUTER !
While installing memory resident from an infected EXE file the virus does not return control to the host program, but displays standard DOS error message "Bad command or file name" and returns to DOS. As a result infected EXE files do work only if the virus is already active in the system memory.
The virus contains the ID-string:
