I'm using Norton, which I've considered to be pretty intrusive up until recently. Like I said, I'll turn it off and install as a last resort. But first I'll wait to see if Noemann or anyone else has a copy they can send me that doesn't include the adware (which I think is what is causing Norton to have such a fit). I wish Norton could filter out the crap and allow Imgburn through.
Norton has never seemed intrusive to me until after instaling Window's 10. Not sure if it's related or not, but that's what I've seen.
