Malwarebytes Anti-Exploit.zip
Basically, after a windows or office patch, this particular user cannot open word or excel because anti-exploit will pop up and give the "Exploit code executing from Heap memory blocked."
When we try to open word or excel again, it says there's a problem with a plug in (box for office) and if we disable it, we can then open word or excel without anit-exploit giving the error.
We've been running all our computers with box for office for a couple years now and this is the only time we've had this issue. I haven't seen this on anyone else's computer either so either no one else did the patch yet, or it's a problem only on her computer.
