I'm sure this is nothing, but I'm curious about it. This item has been in my documents folder for 15 years, but it wasn't tagged until put it on a my thumb drive and it was was plugged in. It has never flagged the same ones in my local Documents folder.

First this one

15 year old Trojan threat blocked-def3.png

Then this, same exact thing, one minute later

15 year old Trojan threat blocked-def2.png

and this one, the next day, related item in the same folder

15 year old Trojan threat blocked-def1.png

Why twice on the same one, and why wasn't the third one identified until the next day? and of course, why after 15 years?
