of isolation is unknown. Beetle is a memory resident infector of
.COM files, including COMMAND.COM.
When the first Beetle infected program is executed, this virus
will install itself memory resident at the top of system memory
but below the 640K DOS boundary, not moving interrupt 12's
return. Available free memory, as indicated by the DOS CHKDSK
program from DOS 5.0, will have decreased by 1,488 bytes.
