What's the difference between Avast's Secureline and a Proxy?

I just signed up for some proxies to open several accounts for things online and now my monthly bill for Avast’s Secureline is coming up. Is there any point to continue? Don’t both the proxies and SL just make it look like I’m using a different ISP? Is there any point in having both?
