I believe I have the exact same problem. First of all I use Kaspersky Internet Security on version: 184.108.40.2068(e) and my OS is Windows 10 Pro 64bit on version 1809. The update reaches 100% but it shows me that it failed. When I press "Failed" and open the "Detailed Reports" window it says: "Update databases and application modules" and below that "Not all components were updated", when I press "Details" I see the error: "Error updating component" and below that the word "KLAVA". The same happens to all the failed updates. Why do I have this problem? Is this a bug from Kaspersky? Thank you in advance.
