I downloaded Advanced System Care…
So, everyone, it turns out that Worthwagon, despite the slightly hokey name, does indeed provide what they advertise: the lowest price out there on the software that they resell. Since I've also purchased Malwarebytes, their PUP blocking feature deactivated Advanced SystemCare Ultimate 14.5 from even installing because ASCU14 runs what they call "good PUPs." It turns out that you can run ASCU14 if you set MWbytes to "ignore detected PUPs" in settings. So, in full disclosure, I'm back to giving Worthwagon a positive rating.
