I had Bitdefender Total Security 2017 and only in safe mode could I uninstall it. Now, I can't fully get rid of it and also Ia in the topic - Ican't install any new antivirus. And after long time of searching(either newer version or some cheap licenses), I, out of lost hope and my stupidity, downloaded something and run it(wasn't sure if it would be malicious or not - it was). Over 2 weeks ago, my antivirus's trial period expired so I wanted to do something about it and download a newer version of it or something like that.

Hello, I really need your help and I was hoping someone here could help me.
