I have downloaded Bitdefender about 6 months ago, I'm not sure if it's necessary(I have Etrecheck too). Bitdefender also seems like it can detect certain viruses, like once I scanned my computer(Macbook Air) with Bitdefender and it didn't remove the adware - although Etrecheck did. I'm not sure if I should delete Bitdefender, or keep Bitdefender.
MacBook Air, iOS 10.2
There are no viruses that can attack Mac.OS X. So, anti-virus programs are selling a cure for a disease that doesn't exist. And they are renowned for borking Mac systems.
A Mac can pick up malware but not if you just use common sense. You really have to actively invite some malware in for it to happen. That means downloading and knowingly giving your password for it to download. Mac provides all the protection you need with SIP (System Integrity Protection).I About System Integrity Protection on your Mac - Apple Support
Keep your security set to “App Store and identified developers” Don’t download software from third party sites.If you use torrents, don't. Torrents are a good way to pick up malware because it can hitchhike in on a download package and you’ll never know it.
Safari pop-ups are different and easier to deal with. In Safari 9.1 and later just close the window. For earlier versions force quit and hold the shift key while restarting Safari.

Finally, do not get fooled by products that claim to clean, virus check or optimize your Mac. If you do happen to download malware you can use MalwareBytes to get rid of it. Malwarebytes was developed by one of our own colleagues here in ASC. It gets rave reviews and is about the most proven anti-malware software for Mac.
Follow the developers instructions to uninstall:
Etrecheck is just a diagnostic device for checking what's running on your system, it does nothing proactively.
No, you don't need Bitdefender.
So I should delete it by moving it to the trash and press "Empty Trash"? Or pressing "Delete Immediately?" By the way I should keep Etrecheck right?

Yes.
Hey it says it uses the administrator password and I once looked at a document(thread) and one guy said that some of the infected files that use the administrator password while installing or so.
By the way should I press "Empty Trash" or "Delete Immediately"?

You're welcome.
