Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill

It does this to try and scare the infected user into calling one of the listed numbers in order to receive support.

Unfortunately, on my first day of testing, I ran into a bug that nearly prevented me from arranging calls. At first, it just seemed like a mistake; on the page where you enter your name, email address and phone number, the last field didn't have the words "phone number," though all the others were properly labeled. Ignoring this, I filled in my information. But then, I got an error reading, "We're unable to schedule your call. Please try again or choose a different solution."
