On-Demand removal tools work regardless of the switch, the switch is for installed, on-access AV products. I think he was saying Zhp wouldn't work or might be a problem because it's not listed on that silly document. It wouldn't be listed anyway, that would be like saying EEK would need to be on it - it doesn't. Also that list isn't properly maintained, I've emailed him directly about a few errors and additions and he didn't fix the list. So it's not the gospel by any sense, but again, it doesn't apply to adware removal tools anyway.
