Unknown links on all pages

Hello, from last week I am seeing so many unknown links on my websites.

All links first appear at the header of the notification area. When I disabled the plugin all links are moved at bottom of the page.

You can check the links at bottom of the page. A white space and when you select it then you will see the spammy keyword
online casino malaysia , online casino malaysia , online casino malaysia , online casino malaysia , online casino malaysia , casino malaysia , casino malaysia , casino malaysia , casino malaysia

I have tried disabling all the plugins and didn’t find the solution.

Please advice…
