This is the strangest offer I've received in a while: Upgrade to CCleaner Professional Plus: a 4-in-1 product with CCleaner, Defraggler, Recuva and Speccy Professional at a 60% discount! What's the difference between all the separate [free] products and CC+? I can't find any documentation distinguishing the paid vs free versions. I'd love to support Piriform and their great products, help me here. Color me 'confused'
