strange files on my computer

I found four strange files on my computer today:
edbres000001.jrs
edbres000002.jrs
edb.chk
edb.log


I understand that these normally having something to do with Win-7
error checking. What I am concerned about is that they appeared in my
Downloads directory. All except the .chk file are the exact same
length (5,120 kb),. The .chk file is 8 kb.) All are time stamped
yesterday, about 5 pm.

Note that these same file names exist in
windows/softwaredistribution/datastore/logs where the size of the
three larger is 1,280 kb. The latest date modified on those is
02/08/2018.

So, what are these new ones doing there, and can I delete them?
