Flip is a rather advanced virus. It is capable of infecting both
COM and EXE files and also the boot sector of hard disks.

Flip originates in Switzerland and was found during 1991.

Systems that have an EGA or VGA capable display adapter may experience
the display on the system monitor being horizontally "flipped" between
16:00 and 16:59 on the second of any month.

The Tequila virus is based on the Flip virus and is made by same authors.
