Firstly I want to say I share a key with another account so this is just my account with no licences attached to it.
I have been using and recommending Bitdefender to everyone since 2016 and the 2018 edition was nearly perfect (apart from a buggy firewall) so when I reinstalled windows on my PC and installed 2019 I was appalled with the garbage software "upgrade" that was this version.
-Performance hit is dreadful compared than any previous version I have used. RAM usage is borderline unacceptable (500Mb+ For just the Security service process) and processes like the "wallet agent" running in the background when I will never use the wallet agent.
-Making a Windows-To-Go USB stick using an ISO downloaded using the official Microsoft media creation tool and half way through the process Bitdefender went and locked a WinSxS component from the iso as a virus and proceeded to close the program do to "Malicious activity" and completely locked the files causing me having to disable every component I could in Bitdefender including the antivirus permanently and a restart to unlock the files Bitdefender was locking. I had to leave every component disabled until I had finished creating the Windows-To-Go stick.
-Bitdefender is causing some sort of weird startup delay of all my programs even though I am booting a heavily optimised windows install with little running in the background (system processes included) and I am booting from an NVME M.2 SSD running in PCIE mode.
-The new interface is a step back like 5 years, everything is everywhere and the configurable options that were inside the individual components (antivirus, firewall... etc) are lacking compared to earlier versions.
I am sorry but as someone who usually has people coming to him asking for advice on which security suite is the best for their computers, Bitdefender has slipped off of my recommendation list due to the amount of frustration that has been caused by the 2019 edition over the past month.
