Has anyone experience with BITDEFENDER Antivirus for Mac, or other?

I have written in another post about the most complete lack of response I have received from Norton to fix my problem over now an entire week. Shoking since the service had been excellent previously for over twenty years.

I have lost a full week of work with an internet connection that is reduced from 1 GB to 50 megs.

Question - what is the best antivirus software alternative to Norton? I am ready to quickly move on as I cannot afford more losses.

Has anyone any experience with BITDEFENDER Antivirus for Mac? Looking for advice for an alternative.

Thank you for anyone who can help.

Intego for macOS works well.   Support is very responsive as well
