(Forgive me if this is the wrong place to post this, but I just wanted to warn people about CCleaner and Piriform. Is there some place I should go to report things like this? I have already expressed my anger on the Piriform forum.)
I downloaded the latest CCleaner update, scanned it for viruses (clean) and installed it. I'm always really careful with installers and there was absolutely no mention of any bundled software. However, it also installed Google Chrome and made it my default browser!
I always thought programs like CCleaner were helping to keep my computer clean from PUPs and crapware. But now I can see that Piriform are part of the problem and I for one will never trust them again.
For reference, here are screenshots I took of the complete installation...
