Can't Install Bitdefender Antivirus for Mac on 2015 MacBook Air Running MacOS Catalina 10.15.4

The problem may be associated with what many of us are experiencing on macOS Catalina 10.15.4, who have successfully installed Bitdefender's Antivirus for the Mac. Here is what is the message I am receiving and it has to do with Bitdefender having an extension that is very old, or considered legacy software by Apple. Bitdefender needs to make adjustments to their software or we who love Bitdefender may have to start looking for an alternative for our Mac computers. I use Bitdefender on my Windows PC and Mac, and would rather not change but Apple may force that, unless Support at Bitdefender updates their code. Here are the messages I see with macOS Catalina 10/15.4 running:

A Notice Form Apple:

"About legacy system extensions

Some systems extensions will not be compatible with a future version of macOS

System extensions are a category of software that works in the background to extend the functionality of your Mac. Some apps install kernel extensions, which are a kind of system extension that works using older methods that aren't as secure or reliable as modern alternatives. Your Mac identifies these as legacy system extensions.

In 2019 Apple informed developers that macOS Catalina will be the last macOS to fully support legacy system extensions, and we've been working with developers to transition their software. By moving beyond these extensions, developers are helping to further modernize the Mac, improve its security and reliability, and enable more user-friendly software distribution methods. A final transition date has not yet been set.

Until the transition is complete, your Mac displays a message when a legacy system extension first loads, and again periodically while the extension remains in use. This give you advance notice that existing software on your system loaded a system extension that will be incompatible with a future version of macOS."

Now also receiving this message from Apple Safari, which may be one of the problems:

"Safari no longer supports this extension.

You can find new and updated extensions in the App 

Store or from developers' websites."

As I am about to renew my subscription for 'Bitdefender - Family Pack' which allows me to have 

"Bitdefender Antivirus for Mac," what support will be provided by Bitdefender for Apple macOS further upgrades beyond macOS latest version "Catalina"? A Bitdefender solution is important for me as well. Let me know if you hear anything. I have posted this in one other area as there appears to be two different conversations on this. If someone in the forum support could consolidate questions and answers in one area to this problem would help.

Same issue to me. Cannot install bitdefender on catalina 10.15.4 MBP mid 2014 and said I should contact techsupp.

Thanks

Experienced similar issue to this. In the past two weeks I've grown to hate Bitdefender. Not at all impressed with tech support on either the Mac or PC side of the house. I finally ended up deleting it from my Windows 10 Pro machine because it kept quarantining applications that were in the exceptions. On the Mac I have this problem, plus everyday it tries to download and install Bitdefender 2020 and it fails. It also fails to install the VPN software. I've used Bitdefender for several years w/o problems but since the last product update it has been a hot mess.
