Recent PAMELA data showed that positron fraction has an excess above several GeV while the antiproton one does not. Moreover, ATIC data indicates that electron/positron flux has a bump from 300 GeV to 800 GeV. Both annihilating dark matter (DM) with a large boost factor and decaying DM with a life around 10{sup 26}s can account for the PAMELA and ATIC observations if their main final products are charged leptons (e, {mu}, and {tau}). In this work, we calculated the neutrino flux arising from {mu} and {tau} that originate from annihilating/decaying DM and estimated the final muon rate in neutrino telescopes, namely Antares and IceCube. Given the excellent angular resolution, Antares and IceCube are promising to discover the neutrino signals from the Galactic center and/or the large DM subhalo in the annihilating DM scenario, but very challenging in the decaying DM scenario.
