We examine the possibilities of accommodating the muon anomaly released by Fermilab in the 2HDM with a discrete symmetry in which an inert Higgs doublet field () has the lepton flavor violation – interactions. We assume the Yukawa matrices to be real and symmetrical and investigate the case of light H (5 GeV 115 GeV). After imposing relevant theoretical and experimental constraints, especially for the multi-lepton searches at the LHC, we find that the muon anomaly can be explained within confidence level in the region of 5 GeV GeV, 130 GeV 610 GeV, and 0.005 0.014. Meanwhile, the fitting the data of lepton flavour universality in the decays approaches to the SM prediction.
