When I try to End Verizon_IHAMessageCenter.exe using Task Manager I get this "WARNING: Terminating a process can cause undesireable results including loss of data and system instability ......"

Should I <really> not END the process this way? How else can I remove it? I tried removing a "rarely used" Verizon app by CP\Add or Remove but that did not remove Verizon_IHAMessageCenter.exe.
