I read the article. However, my hours are not the same everyday; and since I sometimes come down to use the computer in the middle of the night, this doesn't seem like a working proposition for me.
I never changed the settings for scans; so it is apparently the most recent program update that has made this change to the longer scans whereas before it only took about 20 minutes or so. I run the scan manually anyway; so I will run it during the daytime when I am at the computer and hope that ESET comes with an alternative to the long scan time with their next reiteration.
Thanks, Karly
