In recent months, I have increasingly received requests to sign in when I am already signed to my AOL account with my primary screen name. These happen most frequently when I attempt to open My Calendar. They are also accompanied with requests to open a new AOL account, which seems to be absurd since I am already signed in to my account. Obviously I ignore such requests, which usually stop if I switch to another screen name and then back to my primary screen name. Is it possible that these requests indicate infection with a virus or Trojan? My McAfee comes out clean every time. Wilson DeCamp Leesburg, VA
