I used "scan folder" and selected my D: drive, application drive, to scan. The scan itself took an hour and 20 minutes to reach 100%. It continues to scan even though it has reached 100%. I let it scan at 100% for 2 hours and then selected "Cancel". I then let it cancel for an hour and a half and tried to close it via Xing out. Only way to end the scan was to use task manager and end task.
1 Select scan folder
2. Select hard drive to scan as the "folder"
3. When scan hits 100% and continues indefinitely, hit Cancel
