Can anyone help me? (I want to cancel my order)

So basicly, i wanted to try the Avast trial. It wasn’t what i was looking for. Sadly i linked my paypal i don’t remember why and apparently it has something called auto-renewal ? i do not remember activating this AT ALL. I even deleted the anti-virus and moved on. While i was sleeping i receive an email saying that im paying 50$ for the software ??? is there any way that i can get my money back ? I canceled auto renewal already, but right now i just want my money back. Please give me suggestions on what i can do.
Thank you.
