Need help removing antivirus 360 please

How do I remove this bad thing I downloaded. It costs me $80.00 because I have avg but it said I didn't have any viruses and this thing popped up and said I had 37 viruses. So I thought if this found it than my other antivirus was no good anymore so I downloaded this. Stupid me. I need help getting rid of this thing completely out of my computer before it ruins it and costs me a lot more money. Where do I go and get help for free or will it cost me. Thank you.


P.S. It is -10 here now. This is warm for us.
