Having Scanning Issues With Total Security

Just in the past few days I've noticed my scan times getting shorter and shorter. I just rand a full scan and a deep scan and you can see the logs below. A full scan would take over an hour and the deep scan would usually take a little longer. Look at the scan logs on the logs below. Anyone know whats going on here? Why have the scans become drastically shorter?
