Claim:
A method of reducing an avian flu virus population on a surface comprising contacting the surface with a composition for 30 seconds to achieve a log reduction of at least 1.5 against the avian flu virus, said composition comprising: (a) about 25% to about 75%, by weight of a disinfecting alcohol; (b) a virucidally effective amount of an organic acid comprising (i) a polycarboxylic acid comprising citric acid and malic acid and (ii) a polymeric carboxylic acid comprising a homopolymer or a crosspolymer of acrylic acid; (c) about 0.1% to about 3%, by weight, of a gelling agent selected from the group consisting of cellulose, a cellulose derivative, guar, a guar derivative, algin, an algin derivative, carrageenan, and mixtures thereof, and (d) water, wherein the composition has a pH of about 5 or less at 25° C., and is free of an active antimicrobial agent selected from the group consisting of a phenolic antimicrobial agent, a quaternary ammonium antimicrobial agent, an anilide antimicrobial agent, and a bisguanidine antimicrobial agent, and wherein an essentially continuous layer comprising the organic acid is formed on the surface.
