Hi Hopper,
What you've done so far is spot on. I'd suggest running these scans again in Safe Mode though, and turning off your WiFi/disconnect from net when you open your web browsers after the scans to manually change any references to the offending articles before going back online. Also check your extensions/plugins in the browsers to see if there's anything in there.
Give me a shout if that doesn't sort it, happy to help further.
