Hi, my whole multisite got infected by an aliexpress affiliate ad code inserted in html snippet plugin. It infected subsites with with popup ads (dns unlocker + aliexpress and other popups) and in-text ads. Question: Is there a way to protect main site and subsites against other sites who get infected? Wordfence picked it up in the advanced scan, but didnt fix it automatically. I had to delete all plugins in wp-content.
