Not to discount what some may be seeing, but my experience is the same as KidJoe's for whatever that may be worth. I have Win10 and Defender is updated - no notice at all during the update process via the auto-updater. Manual scans of \Program Files\DVDFab, \Users\\AppData\Roaming\DVDFab, \Users\\AppData\Roaming\LiveUpdate , and \Users\\AppData\Roaming\StreamUpdate also find no malware, PUPs, etc.
