Not sure exactly what files were prevented from loading, but Malwarebytes identified a PUP in the downloaded pdfcreater 2.0 and quarantined the files. It was named something with “monetized” in the title. Why are PUPs being placed in pdfcreator?
it was most likely the installmonetizer which is used to load and display an offer screen during setup. Nothing will get installed without you accepting, but displaying an ad during a setup can be called potentially unwanted. The reason why the setup contains this at all is simple: The software is free but the development costs lots of money. It is possible to purchase an ad-free version of the setup for a very low price here: http://www.pdfforge.org/pdfcreator/plus
