I can't seem to determine where the problem is coming from.
Theme, apps. page/s or product page/s?
I checked the source and I'm seeing suspicious iframe codes on the product description section, even those products showing on 'related products'.
But if I check the codes on rich text html editor, it's clean, there's nothing suspicious.

Can someone help me on this, please? The store link is www.unicornchasingrainbows.com
