Hi Hokie,
Looks like Defender has "forgotten " it has done a scan .
This may be because it's log files are being cleared.
Do you use some sort of cleaning utility, like Ccleaner ?
If so, check it's options to see if it is clearing Defender logs.
Hope it helps

Thanks for quick reply. I do not have Cleaner on this PC. Did on old Sony with XP. The only cleaner I think I have is MS disk cleaner which I used only once but recall not selecting any log type files to be cleaned. How do I check the defender log to see if it has entries?
Thanks, Hokie 56
