Before version 5.45, I always had four Piriform products on my system - CCleaner, Defraggler, Recuva and Speccy. As of today, only Speccy remains - and I'm actively looking for a replacement for it. These programs have been on my system through 4 PCs and numerous versions of Windows. To uninstall them - that's how much trust I've lost in Piriform since CCleaner 5.45.
