Hi, i continuously see annoying pop-up windows that change a few URLS in the address bar until a final site is reached.  One of the URLS that i noticed was Go.padsdel.com, I believe. These Go.padsdel.com pop-up ads are hideous! Some of them advertised some suspicious ero-themed game, others pointed to sites that advertise MacKeeper, and others pointed to gambling sites. HELP ME TO STOP THIS. Please.
