The update function within defender is supposed to popup a balloon in the
notification area and sound an alert ping. The balloon first says WD is
checking for updates, and for instance if none are found, a second balloon
pops along with a second alert ping saying WD found no updates. Is it
possible you have balloon notifications turned off on your system?
