I am running Kaspersky Internet Security 19.0.0.1088(f) on Windows 10 Home x64 Build 17134 (which is fully up to date with all updates). KIS has 351 days of license left (I recently renewed).
On a daily basis the auto update fails at some point and it is always a failure to update KLAVA (whatever that is!).
The problem occurred before I renewed but have waited until after renewal to see if that fixed the problem - it did not.
I have tried the following which I have read about online, none of which have solved the problem:
I have re-installed KIS (twice)
I have turned off gaming and proxy server settings (I use neither)
I have renamed the KLAVA folder to KLAVA.BAK
After the reinstallation and the KLAVA renaming the updating worked for a few hours then failed again. Turning off the gaming and proxy settings made no difference.
After starting my PC each morning the updates initially work then fail at some point a few hours later having successfully performed some auto updates.
After an update failure if I reboot then re-run the update that works - then it fails again a few hours later after successfully performed some auto updates.
I cannot observe any patterns to this - for example how many auto updates work before a failure, or if the failure is at any particular time of day (it appears random).
I am not doing anything out of the ordinary on my PC - just browsing (Firefox), emailing (AOL on Firefox), using Word/Excel and photo editing (Capture One Pro, Photoshop Elements etc.). I have been running Windows 10 for a couple of years so that has not changed - other than its automatic MS updates.
So...
Any suggestions about how to fix this would be appreciated
If the KLAVA update fails does it mean my KIS database does not contain and use all the latest definitions etc. (i.e. I could actually ignore the failure) as the KLAVA folder seems to contain mainly log files of some sort?
