ABSTRACT:
A method includes randomly mutating a virus definition file on a first host computer system to create a first mutated virus definition file, and randomly mutating the virus definition file on a second host computer system to create a second mutated virus definition file, the second mutated virus definition file being different than the first mutated virus definition file. Because of the differences between the first and second mutated virus definition files, a new unknown virus variant undetected on the first host computer system is detected and collected on the second host computer system thus preventing the unknown virus variant from becoming widespread.
