Thank you for your timely reply, though I was preferably eliciting a response from an admin, or better yet the apps dev(s).
I didn't mean my actual anti-virus program (which is Avast too, btw). I was using that term loosely. I meant one of the most popular anti-malware applications for Windows available, MalwareBytes Anti-Malware, which by the way you should know of given your "30 years deep and wide IT experience". MalwareBytes flags it as "Optional.OpenCandy" which it would have no reason to warn me if there was not a potential problem or threat (it's not known as one of the best for giving false-positives).
I'm well aware of how OpenCandy works. The primary reason that developers wrap it around their software is to monetize their "poisoned candy" i.e. "mal-ware, with freeware as bait". As you implied in your comments more people would accidentally click through a free product ("Hurry, hurry! Gimmie, gimmie that free candy!!"), than be willing to pay a fair price for it, so it's more lucrative for the dev(s) to use OC than to actually charge a fair fixed price...which I find very frustrating because licensing "clean" software out to users is much more ethical if not lucrative to do than throwing out mal-ware infested "candy".
It's a shame this is common place, because some of the free software wrapped in OC installers are otherwise REALLY GOOD! Take Freemakes (http://www.freemake.com) software for example. Their Video Converter is AMAZING! DXVA and NVIDIA Cuda accelerated, beautifully simple, functional, and clean interface, well-coded -an altogether excellent app. That too along with all its sister apps is infected with OpenCandy! Fortunately, I got ahold of the devs and was able to find a "clean" version I could purchase.
In fact, I've talked to several developer's of software I use regularly, either by phone or by email, and all of them have always had a purchasable ad-free version of their software available, where I could buy. I'm reaching out to the developers of ImgBurn in somewhat the same way, albeit less personal (I don't have any contact information for them).
I hope you can understand.
P.S. When you said "srill" did you mean "shill", as 'srill' is not an English word. :-)
