Thanks. It was while I was visiting a forum. All I did was select the Yes button by checking it. I have MSE, updated. I ran a full scan with that and also with Malwarebytes Antimalware, SpyBot S&D, and Ad Aware. Perhaps it was only six seconds, not 15. Six sounds more like it. I will now also run Rkill..................................... aaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaa As you can see, my computer does not prevent doubling up on letters. I also held the Shift key for six seconds.
