JDC family

Description JDC family

These are nonmemory resident polymorphic parasitic viruses. They search for COM and EXE files in current and parent directories, then for the COMMAND.COM file and write themselves to the end of the file. While infecting files packed with PKLite the viruses patch PKLite entry code and write "JMP Virus" instruction into the middle of PKLite code.
The viruses use two levels of polymorphic encryption as well as anti-debugging tricks based on i386 features. Under debugger they display the message:
This program requires 80386 or better.

The viruses also contain the text strings:
A JDC PRODUCTION
~~TEMP~~.TMP
