Summary
When the virus activates on a computer with an EGA or VGA display
adapter, it will "flip" the screen horizontally and switch to a special
character set, which reverses each character. This effect only happens
on the second day of each month, between 16:00 and 16:59. The Tequila
virus is clearly derived from Flip, and is probably from the same
author.
Flip contains this encrypted text: "OMICRON by PsychoBlast".
