Has this ever happend to you/your computer?

<p>This just happened for the 2nd time in about a week – I went to a website (this time I went to the Celtics website to check the score; last week it was a completely different site) and almost immediately after the site comes up on the screen, a gray “overlay” rolls down the screen, from top to bottom. It’s like someone is pulling a shade down over the screen. Then a message box shows up in the center of the screen saying something like, “You need to shut the power off to your computer. Hold the power button down for several seconds or hit the restart button.” – and it says this message in several different languages. The cursor disappears and everything is frozen, so the only thing to do is, in fact, turn off the computer with the power button.</p>

<p>This is on a Mac with up to date virus software. Anyone else get this? Any thoughts?</p>

<p>I have a MAC and I had a problem with certain sites when I updated my norton software. I didn’t notice because it happened so gradually. The computer became slower and slower with certain sites until the little disc just went into permanent spin and would never connect. I learned what the problem was by calling Apple’s help line. I turned off the firewall but left the virus protection on.</p>

<p>CBB- Just in case, I’d back up the computer if I were you. My s just lost his harddrive and hadn’t backed it up in a long time. Not fun. Had to reinstall everything- lost all his data. His biggest disappointment-- lost all his music. Too bad.</p>

<p>like this?

<p>ek – that’s it, exactly!!! Thank you SO much! I just knew it would be more efficient to throw this out to the CC world.</p>
