General Comments:
The Druid virus was submitted in October, 1992. It is a non-resident
direct action infector of .COM programs, but not COMMAND.COM. It
overwrites the beginning of the programs it infects, permanently
corrupting them.
When a program infected with the Druid virus is executed, the Druid
virus will infect all of the .COM programs located in the current
directory. Once it has completed infecting the .COM files in the
current directory, it will move up one directory at a time in the
directory structure, infecting programs, until it finally infects
the current drive root directory. It avoids infecting COMMAND.COM.
Programs infected with the Druid virus will normally not increase
in size. The exception is that if the original program was smaller
than 317 bytes in length, the program will become 317 bytes in
length. The file's date and time in the DOS disk directory listing
will not be altered. The following text string can be found within
the viral code in all infected programs:
"DRUID, coded by Morbid Angel/Line Noise"
Systems infected with Druid will notice long disk accesses occurring
when .COM programs are executed. The long disk access is due to the
virus infecting .COM programs in several directories. Infected
programs will not function properly.
