It is a very dangerous nonmemory resident encrypted parasitic virus. It writes itself to the end of .COM files. Being executed the virus searches for COMMAND.COM file by scanning Environment area for the COMSPEC= string, then it searches for *.COM files and infects them. On July 1st the virus erases the FAT of the C: drive. Depending on the system time it displays the message:
This program requires Microsoft Windows.
and returns the control to DOS instead of the host program. The virus also contains the strings:
*.COM COMSPEC=
