The Hindu mentioned that "the screenplay is incoherent in parts" and that "the dialogue and expressions are sometimes too clichéd". She blamed the film's production delay revealing that "initially the film did kindle a lot of interest — what with A. R.

Chennai Online wrote "So, while taking a lot of effort to put in style and gloss, Kathir forgets to put in even half the effort in his scripting and narration. The scripting is slip-shod, the narration is jerky, and leaves much to be desired. The director totally ignores the time factor, and the continuity in logic, between scenes preceding and those following".
Sify wrote, "Blame it on the avalanche of love stories hitting the screen in recent times that directors seem to have run out of ideas. Kathir, the much hyped director wanted to try out something different with
Kathal Virus, but has ended up in making an intolerable film". The critic added, "the music of A.R.Rahman does not fit into the narration. The lead pair is a total letdown as Richard and Sridevi looks wooden and uncomfortable".
Cinesouth wrote "Cinema means business for some. To some, it is a form of art. For director Kadhir, cinema is poetry. He cant make a film without love, without poetries, without extreme close-ups of roses in bloom and without love letters getting mixed up. 'Kaadhal Virus' has all these ingredients." The film became a box office failure, with Kathir feeling that having "Virus" in the title was wrong since it possibly led audiences to believe it was about
computer viruses. == References ==
