The scan took 9min 28sec for the same data size, slightly slower again than the previous one in reply #32.
Seems that all tests are conclusive: scanning speed is
not higher.
Closing the SUI allowed the logon to complete, when all had settled the Scanned total: was 117, so a big difference in the scanned total when avast at logon was run having only logged off/on to initiate the scan. So it is strange that even though there are less files scanned in the background by standard shield the on-demand scan was slightly slower.
It's difficult to make a correlation between speeds right now.
I think defragmentation at logon time was significantly better with Windows 9x and Me.
Maybe things are different on NT platforms.
So overall for me there doesn't appear to be much difference if I do a normal on-demand scan or use the avast on logon scan, it may well make a difference for someone with more programs running on boot/logon.
My case is, obviously not yours, I have a lot of background processes.
Tech, forgive my ignorance but does it include an uninstaller? i.e: could we uninstall it?
It's a standalone. If you want to disable scheduling you could: boot and cancel the scanning or just schedule it twice. An option to unschedule will appear.
