Kadhal Virus (transl. Love virus) is a 2002 Indian Tamil-language romance film written, directed and produced by Kathir. The film featured Richard Rishi, Ajith's brother-in-law, and Sridevi Vijaykumar, Vijayakumar's youngest daughter, making their acting debuts in the film, with Abbas in a supporting role. A. R. Rahman composed the music for the film, while Arjun Jena was the cinematographer for the project. The film tells the story of a young director, trying to pursue his dream by overcoming all hurdles. After much delay, the film opened in December 2002. Unlike his previous two films Kadhal Desam (1996) and Kadhalar Dhinam (1999), Kathir's Kadhal Virus was panned by critics and fared poorly at the box office.
