It's hard to tell you anything as you fail to mention some rather important things such as the name and path of the infection, what pop-ups you are getting if any, your operating system and service pack and what McAfee products you have installed.
As you mention Stinger I assume you don't have any McAfee products installed anyway. Stinger is good only for a limited number of infections.
