When a file infected with Tequila is executed, the virus infects the master boot record. In a manner similar to Flip, the virus reduces the size of the disk's partition by 6 sectors and placing its code in the sectors that are outside of the partition. When the disk is booted, the virus becomes memory resident. When .exe files are executed, the virus appends its 2,468 bytes to them.
It will not infect files with the letters "sc" and "v" in their names. This is probably to avoid infecting antivirus programs.
The virus displays the message:
