These are dangerous memory resident encrypted parasitic viruses. They hook INT 21h and write themselves to the end of .COM files that are executed. The viruses do not infect the files: VSAFE.COM, COMMAND.COM, WIN.COM. They have bugs and install themselves two and more times in the system memory, as a result in some time the system halts.
The viruses contain the text strings:
SUCKER
.COM VSAFE COMMAND WIN
"Gigi.1449" contains the texts:
