These are very dangerous nonmemory resident parasitic viruses. They search for all files of the current directory by using the mask "*.*", then write themselves to the end of the file as they are infecting COM files. As a result the non-COM files halt the system being executed, and data files may be corrupted. The viruses display the messages:
"Haldeman.431":
Fortisan et nostrum nomem miscebitur istis

"Haldeman.614":
We should change that a little bit. Johns point is exactly right.
The erosion here now is going to you and that is the thing that
we have to turn off at whatever cost. We have to turn it off at the
lowest cost we can, but at whatever cost it takes.

They also contain the text strings:
"Haldeman.431": Ovid Fortisan Virus Thespian
"Haldeman.614": Haldeman Virus eMpIrE-X
