Tequila is a DOS-era multipartite computer virus discovered in 1991. It infects both executable files and disk boot sectors, allowing propagation through infected software and bootable removable media. Tequila combines several advanced evasion features for its period, including stealth techniques, polymorphic code, tunneling, and anti-antivirus behavior intended to hinder detection and analysis. It also includes a visible payload that can display a Mandelbrot fractal. Tequila affected IBM PC-compatible systems running DOS.
