Like I said in previous comments. Nothing is better than report bugs, annoying features, vulnerabilities or undetected malware to them. Use the proper channels to do it, I mean use Reddit if they are on Reddit, Go to Forum of BD and report, send a Ticket / Contact support.
This is the best way to have an update or fix. Complain in Blogs or Forums they don't see or don't visit, won't help nothing. That is the truth.
If you can do it, join more people with the same problem and complain in these proper channels.
And if you have suggestions about new features you want to be implemented you should give it on Reddit, Forums and Support Tickets.
I just would like to see a better feature against desinfection, like Kaspersky a Rollback should be very nice in BitDefender. I mean I would like to see improvement in these feature, even if they have. It needs to be improved a little more.
BitDefender is not buggy, is doing it great. At least their Web Protection is one of the best IMO.
