I moved this to VirusScan as that's what it's about.
The first time you scan it always takes a long time but a scan will be shorter as time goes along as it glosses over files that haven't changed since the last time.
As far as the schedule switch is concerned that's probably due to a major update resetting it back to default.
All I can say is sorry for the inconvenience.
I could swear that scheduled scans have been full prior to this update. I base this on the number of items reported scanned in the security report. And the scan time had not gotten shorter over time.
But if that's how it is, then so be it.
I will continue to do manual full scans regularly anyway.
Well you could always run the Virtual Technician to make sure all is well, link below and further down that page
you'll see the contact button for Technical Support should you need them.
I'm seeing the same thing. Scan schedule was changed and only about 1/10th the number of files are being scanning. I wonder if changing the Real Time Scanning setting to Programs and Documents only then back to All Files would fix it.
Try it but I don't think this is abnormal as explained earlier.
If you are worried about it and running the Virtual Technician (suggested earlier) didn't help then open a case with Technical Support, its free and you can ask for excalation if it isn't fixed at first.
