I was looking over my bank statement and came across a payment to AVG UK for $5.99:
"google*avg UK g. Co HELPPA#AU
Payment Fri 13th September, 11 September 2019 Approved.
I have not downloaded any items, applications etc from anyone to any device, and certainly not from AVG and certainly not approved this payment. How do I stop this happening and get my money back?
