I have just updated the CCleaner free edition to 5.23.5808 an it installed unwanted software, Google chrome and the Google BHO for Explorer. It did this silently and there are no options to decline the offer or nor is it mentioned in the software agreement that I could see. Unchecky didn't pick it up and I uninstalled the crapware manually. Something you might want to check. I've been using the CCleanrer for a while now and found it to be good honest software. If this is the case with the unwanted software issue then its a pity.... might have to try something else. Come to rely on Unchecky to pick this sort of thing up. It's a good solid, effective and unobtrusive little app. keep up the great work and Thank you.
