My issue turns out to have been long running AV scans and potential small disconnects. I would kick off the Full scan and believe the statement “Scan scope: All internal disks and currently running applications”. As it starts to scan my network drives any network hiccup causes Kaspersky to stop making progress on its scan the UI makes it seem like it is stuck. desktop02:Volumes jgarcia$ ll total 0 drwxrwxr-x 7 root wheel 306 Oct 31 19:24 Backup Data lrwxr-xr-x 1 root wheel 1 Oct 29 06:48 Macintosh HD -> / drwxr-xr-x@ 3 root wheel 96 Oct 16 00:13 Recovery drwxrwxr-x 7 jgarcia staff 408 Oct 27 13:19 USB02 drwxr-xr-x 3 root wheel 96 Oct 31 19:24 com.apple.TimeMachine.localsnapshotsIn this example Backup Data is my NAS, USB02 is just a USB drive, and the final one is com.apple.TimeMachine.localsnapshots. My NAS is relatively large and that would probably never finish. USB02 gets scanned very quickly. The final one local snapshots only gets created when the Time Capsule “Back Up Automatically” is enabled this enables hourly incremental backups. The final one also appears to. be problematic Finder makes these look like external drives but I’m not too familiar with how Time Capsule treats these however having these being present also caused issues for me. My takeaway for the time being is to turn off “Back Up Automatically” and unmount all network drives when I want to perform a Full Scan although not having to worry about this would also be nice.
