Ok so while on Mapquest and Facebook today, Safari was acting very slow... I even had to Force Quit it once or twice because it stalled. Also, when on Facebook, a cursor appeared that I've never seen before. To the lower right of the arrow appeared a blue ball, like the BMW logo, but instead of blue and white, dark blue and light blue. Does anyone know why this is or has anyone seen it? I tried searching, but no luck... I'm afraid it's a virus or something...
