  The non-observation of neutrinos by the IceCube at the Glashow resonance
energy of 6.3 PeV has been a long standing unresolved issue. In this paper we
propose a t-channel neutrino absorption by the C$\nu$B, which causes a cutoff
at 4.5 PeV neutrino energy, to explain the IceCube observations. We present a
neutrinophilic 2HDM where the neutrino masses are generated by a low scale
seesaw mechanism. A $\mathcal{O}$(10) MeV scalar mediates the interactions
between left and right handed neutrinos and generates the t-channel diagram
used for explaining the absence of Glashow resonance. The same scalar mediates
the annihilation of the dark matter and generates the correct relic density.
