Little Pop up then disappears
I was wondering if anyone experiences while on the internet, a little pop up window, that appears and then disappears very quickly? It's so fast that I can't make it out.???? Spyware??? It occurs very frequently. It seems to happen after I click on any result after a Google search, and even on a yahoo search result. This seemed to start happening after I upgraded to OS X 10.6.4
Thanks for any ideas!
