Something does appear strange!.
I keep getting pop-ups about latest download for CCleaner, yet clicking on the version installed on the computer, there is not the usual 'new CCleaner' download mentioned.
Another point possibly to be aware about, is the previous update I was informed about, led me to the cnet website for the download. I know I have had problems downloading from cnet with unwanted items being installed alongside the program originally intended. There as been a mention about this cnet problem on this and other forums.
