My system had been experiencing a number of problems beginning with a sluggish typing response in message windows which increased to a dead stop, then froze the screen entirely. I had to exit USMB to escape it. Then there was spontaneous audio that sounded like a tv commercial. The only way I could get rid of it was to kill my speakers. Then, while typing, certain words and combinations of words became red and underlined. Then each time I tried to log onto USMB a full page spoof with FlashPlayer logo was demanding I DOWNLOAD it -- which I would not. That had me locked out of USMB all day yesterday. I took no action. But today I addressed USMB and, voila, everything seemed back to normal -- with one exception; two rows of red, underlined words and word combinations at the bottom of my screen, same as those mentioned above. Scrolling over these words causes pop-up ads. Any of that seem familiar to you?
