[Failure to add root certificate to all known browsers ( 9.0.349, W10-1511)]

@ Opti Yes ..that is eaxctly what I did and the problem has not returned since then.

 

I dont think I even had the original/known certificates for some reason so could not have folllowed Marcos advice above (brand new Windows 10 Pro x64 machine)

Guys..I put SSL / TLS filtering into interactive mode...accepted all the scan questions as they came up at boot ( said Ok to scan) and then waited about 5 minutes, rebooted and put the filter mode back to automatic and it no longer starts with the error. Thanks Marcos for reply. Not sure what the real answer was for this but issue has gone for me at least.

I too have this issue. Newly built Windows 10 Pro machine....installed Firefox and then ESET Smart Security  9.0.349 and this error now pops up on every boot. it does disappear if I disappear if I disable SSL scanning.I am hoping I have correctly managed to collect a log and will send it via pm to Marcos as well
