Good Evening bekkif18 and welcome to CH
OK this question is better suited for the folks on are malware / virus section
But If I may I will give you my opinion
in my opinion speedypc is a waste of money and they are out of there mind
IN my opinion Avast, Malwarebytes and Vipre are all great products
Avast comes in free and paid version
Malwarebytes also comes in free and paid
Vipre offers 2 weeks free and yearly cost is very hard to beat and it is one of the cheapest if you have multi PC's in house.
I hope this helps but like I said I would stop by and post on the malware / virus section

I hope I was able to help you.
