Virus is an Argentine new wave music band, led by Federico Moura until his death on December 21, 1988, from AIDS-related complications. His brother Marcelo then became lead singer, until the band gave its final performance on September 29, 1990, in a support slot to David Bowie. Virus reunited in 1994 and has had some sporadic activity, without recovering its previous popularity. Their latest album, Caja Negra (2006) features live versions of their classics, together with 5 new studio tracks, with invited artists influenced by the band: Ale Sergi (Miranda!), Adrián Dárgelos (Babasónicos), Pity Álvarez (Intoxicados) and Ciro Pertusi (Attaque 77).

Moura was a talented frontman, regarded as one of the best voices in Argentine rock. This, together with an ensemble of talented musicians, allowed the band to revolutionize Argentine rock. Roberto Jacoby wrote the group's lyrics from its beginning. Some of their best-known songs are Wadu Wadu, El rock en mi forma de ser, Hay que salir del agujero interior, Una luna de miel en la mano, Amor descartable, Imágenes paganas and Mirada Speed.
