I’ll give you a definite “maybe”, leaning towards “probably”.
Install the WordFence plugin and have it scan your site. See what it thinks.
Hi,
Thanks for your (again) very fast answer…
I have an other security plugin (secupress) and the scan is ok…
But at this time strangely i have an issue with the firewall of this plugin i don’t know why…
I already scanned my websites with avast on my laptop and nothing special came out.
So, maybe i ‘ll instlall quickly wordfence and try a scan just to be relax.
And delete thoses files anyway after.
Let see …
Thanks !
So nothing came up with the scan of wordfence.
I was embarrassed cause i didn’t see in the wordfence scan the wp-content folder, but wp-includes and wp-admin (for finding unknowed files)
I checked the options but did’nt see something to activate this, i guess wordfence did his job anyway and everywhere in the wp files…
(I activated in the options “scan all files/external files of wordpress” in case of)
Anyway, i scanned again thoses css and js files at virustotal.com , all is clean.
I removed them from my ftp, and the websites works just fine.
I keeped thoses files in case of, cause there were theme’s js fonctions and galeries options scripts i guess.
