Normally when a System Scan starts, it churns through the files at a reasonable rate, finishing the scan of my single hard drive in about an hour or less. Today it started, then stalled at 4%, displaying:
	File: c:\Windows\System32\wshbth.dll (which is a 32 kb file)
	Scanned items: 237 (and not increasing)
	Elapsed time: 24:12 (and increasing)
	The hard drive light is not solid green (which it usually is during a system scan), but is in fact mostly off unless I do something else in some other program to access the hard drive.
	I updated Bitdefender Total Security 2019 and restarted the computer, but nothing changes. The display in the Full System Scan window does not change except for the elapsed time. A Quick Scan runs and completes with no problem. Previous System Scans completed successfully.
	Edit >> Windows 10 Pro, fully updated.
	I haven't changed anything on my computer recently. Is this a Bitdefender problem?
	Thanks,
	John B.
