Problem with Kryptik.co on my website

[JoseTicTag 0]

Hi from Spain, we have making a website https://www.aramur.es, and our client when is visiting it, the ESET security launch an advise: js/Kryptik.co is detected.
I have searching for a solution, but nothing seems to work. Checking the logs on server, download all the archives, upload plugins, checking with online scanners and nothing.
So, is there any chance to move the URL into a trust zone or something in the ESET or asking for a delist from a data base.

Thanks so much for your time.

The detection is correct. At the beginning of the main page there is an obfuscated ad-related javascript that was most likely injected somehow there without your knowledge. Does the domain "ads.voipnewswire.net" ring a bell with you?

No, we think that in some line of a php archive from any plugin is infected. But no way to know wich one is the infected one.

Is there any posibility to know with ESET?

Thanks.

I would start with any WordPress plug-ins you are using. The "free" ones do have a reputation for containing malware.
