Ok, Thank you.

Finally, I stop its visibility of Helpful & unhelpful comment review on my site https://webmarketingtools.com

Ok thanks 

But it won't stop this script which will increase my loading time.

.user-review-vote{display:none !important}

you can place this in theme options - general options - custom css

Here is the website link.

https://insidehost.net/hosting-company/hostinger/

We are not able to check sites by screenshot. Direct links are required

I've attached screenshot.

It is product/shop page which we create by adding new products.

you missed to send link, so i don't know where you have this

Please reply me here.

How can we remove this whole script of Helpful or Unhelpful review?

If we don't want to show it.
