We study an electronic model of a two-dimensional {ital s}-wave superconductor in a random potential using quantum Monte Carlo simulations. The superfluid density and the strength of the delta function in the optical conductivity are found to vanish beyond a critical disorder. We calculate the temperature-dependent resistivity {rho}{sub dc}({ital T}) for a highly disordered interacting Fermi system. Using this we identify the nonsuperconducting state as an insulator. {copyright} {ital 1996 The American Physical Society.}
