PastorL5's solution below worked for me except I didn't have to restart Safari. While Safari was open, I held down the command key while pressing the W key a bunch of times. That got rid of the Major security Issue call 800-680-4131 box and I was able to use Safari as normal again. The problem originally occurred when I tried to watch a live tv show for free online and downloaded what appeared to be MPlayerX.dmg, but I think it was just a virus. Before I tried this solution, I had put that dmg in the trash. I don't know if I also need to remove other files from my ard drive. Does anyone else know?

Kellen, when as Safari was opening I held down Command and repeatedly hit the "W" key to close all the windows Safari had opened and it fixed it right up!
