Help with removing "Discountman"

Hey Folks, I keep getting popups by this weird spyware called "discountman". When I google it, it tells me to do things I have already done like remove it from my Chrome extensions, manually delete the extensions folder from my C: drive, and scan my computer with various spyware programs (see link below). However, it goes fine for a couple of days but then somehow manages to come back. Has anyone else encountered this "discountman" bug?

I have done all 5 steps from this link...
