How to search image that contain malware, in post. Google sometime report this to us

[BirdOPrey5]

I don't think the actual image contained malware. I get google warnings from time to time and the problem is someone linked an image in their post from a domain google knows to distribute malware. Even though the image itself is safe, Google sees the link to the bad domain and puts a warning on your page.

There's not much to do about it short of not allowing your users to post images.
