Boot scan file definition updates never ending for hours?

[jraju]

Hi, I opted boot scan and in the process, clicked the button to update special definitions for boot scan. There was progress bar going from left to right. I waited that to complete. Even after about an hour, the screen does not complete.
I just closed the screen.
Before rebooting , i just again opened and tab the boot scan options, now, i was alerted that all the requisite definitions have been updated. please see this . Is it for everybody or to me only
