Well, is it? Is your answer – “what the hell are you talking about?”
It turns out that thousands of hacked sites are infecting Google image search results with images redirecting to Fake AV sites. And, unfortunately for you and for me, WordPress sites are a prime target for this kind of attack. A PHP injection into a WordPress site can generate spammy websites, hijack Google Image SERPs and result in your WordPress website tossing unsuspecting Google Image searchers to a FakeAV site.
Depressing, right? Might be time to check your website to see if it’s been hijacked in this way.
