71A selection study in treatment naive HIV patients to compare the virologic success rate of once daily antiretroviral treatment regimens at the 48th week with Epzicom(lamivudine and abacavir) plus efavirenz and Epzicom plus ritonavir boosted atazanavir. The superior regimen will be hired to the comparative study to the current first line regimen (tenofovir plus lamivudine plus efavirenz)
