How to remove AddToAny plugin completely

Dear Sir,

I used AddToAny plugin on my website and placed it on WP Single page via the plugin’s settings.

After I uninstalled and removed the plugin, the sharing links to Facebook, Twitter, Pinterest, etc. are sill existiing on single pages of my website.

I know the above by checking:

Google Chrome –> Inspect –> Network

Then:

Google Chrome –> Page Source

I found this container in HTML codes still active Single page:

<div class="social-container">
 ----------------
</div>

It contains links to all sharing buttons mentioned above which slow down the load of the single page. Here is example a link to Twitter:

<a href="https://twitter.com/share" class="twitter-share-button" data-url="https://www.mydomain.com/post/%e1%9e%8a%e1%9e%b8%e1%9e%9b%e1%9e%80%e1%9f%8b%e1%9e%93%e1%9f%85%e1%9e%81%e1%9f%81%e1%9e%8f%e1%9f%92%e1%9e%8f%e1%9e%80%e1%9f%82%e1%9e%94/" data-lang="en">Tweet</a>

Can you please advise how to remove the above container from my website.

Many thanks in advance.
