I was not sure where to post this so I am trying here. This is the second time this has happened and I am unsure as to what is happening. Ok... here is what is happening: Cruising a variety of sights in Safari, suddenly, 1)Safari minimizes into a small window in the lower left of the screen; 2) a dialog box opens up warning of Data loss. Options are Cancel and OK. When you choose cancel Safari goes to another website claiming to scan your computer then tells you you must install. Naturally I close the window to ignore it, then 4) another box similar to the first one opens. It has no option except OK. No way to cancel. I am forced to Force quit Safari to get rid of it. Any ideas? I have included screen shots.
