Need to cancel 'Avast Premium Security (Formerly Avast Premier) 60 day trial

Hello,

I signed up for the 70 day trial using my
PayPal and without realising the avast used my paypal email which I hadn’t bothered to change. The thing is my PayPal email is extremely old, so old to the point I cant even access the email anymore. I really need to cancel this subscription as I cant afford to pay the fee when the trial runs out.
Can anybody help me please?
