I scan my website using different tool but it shows no malicious script. But when i see in admin dashboard i see strange symbol square below body tag.
i tried to check admin index file,root index file but there is nothing there.Some one place this script.
Also when i tried to take backup its not allowing me to take.using backupwordpress plugin. how ever all other things working but still some thing wrong in admin.
HOw to detect and remove this.
