This is a 1077 byte virus, which infects .COM files in an ordinary way, but .EXE files are infected in a similar way, which prevents the virus from infecting .EXE files longer than 64K. The virus was written in Scotland and is known there as "Murphy", but this name should not be used, as it may be confused with the totally unrelated Bulgarian Murphy virus.
