The purpose of this study is to look at the safety and effectiveness of a pill called Trizivir that is a combination of three anti-HIV drugs (zidovudine, lamivudine, and abacavir). Zidovudine and lamivudine are often given combined in one pill (Combivir). In this study, Trizivir will be compared to Combivir plus abacavir.
