Before you run a boot-time scan, you are advised to install specialised definitions. If you click the button to do this, a horizontal line moves back and forth, presumably to indicate that these definitions are being installed. I've tried to do this on two computers this weekend: an HP laptop and a Dell desktop. In both cases, the line was still moving many hours later - in fact, for most of the day. It's hard to believe it could really take this long. In the end I gave up waiting and just did the boot-time scan anyway, which in both cases found problems. But the suspicion remains that it might have found more problems if the definition installation had terminated.
What is going on here? Does it really take more than a day to install these specialised definitions? Or, more likely, I suspect, was it stuck in some loop or just stuck doing nothing. Is there a fix?
