I changed my AV from ESET to Bitdefender 2019. I also use Zemana Antilogger (not antimalware) since 4 years.
Since I use Bitdefender, I am unable to update the signatures database of Zemana Antilogger.
Zemana told me that BiDefender blocks these updates. So I made a test by disabling all functions of Bitdefender and the Zemana signatures updates are OK.
So, how can I Set BitDefender to allow the database signatures update of Zemana antilogger ? It is not two concurrent products. The Zemana antilogger is not an AV nor a firewall.
