Version 20.0.0.829 iMac v10.13.6 Kaspersky updated yesterday and seemed to be running fine. This morning, it said not all Kaspersky components were running and suggested I reinstall (or contact support). I updated and the system rebooted. Still problems with "not all components are running". Note, this same "not all components are running" behavior is showing up on my iMac (v10.13.6) and my MBP (v10.12) this morning. I downloaded and re-ran the install on my iMac. The installer script is stuck at 78% installation.

Some console log information: failed to fetch /Library/Application Support/Kaspersky Lab/KAV/Applications/Kaspersky Anti-Virus Update.app/Contents/_CodeSignature/CodeTopDirectory error=-10

Ok, the install finally completed (took roughly 20 minutes total). It does not make sense why it had to re-install the exact same version because the kaspersky self-requested update failed.... maybe the prior update (yesterday) was incomplete. In any case, it's up and running now.
