How to get rid of webhp? trojan/malware?

I've been trying to get rid of webhp? redirection in google chrome for os x for a while now, I scanned the whole system and found nothing, I disabled all of the extensions, cleaned cache — basically did everything I could think of, and I still get that redirection sometimes when I search for something using Chrome (it doesn't happen in Safari or I didn't notice that).

Adware is quite the problem today even on OS X. See my signature for a removal tool.
