I can confirm this problem has been fixed, Thanks Dave.
The installer [in my case] was wanting to install AVG with Ccleaner. I wish piriform [and all other companies as well] would stop this practice of packaging unwanted software with other products. I do not care for AVG and if I change my mind in the future I already know where to get it.
I did not know MS now has a GUI to change this PUA option so at least I learned something new. Even with the GUI making it very easy to turn on/off PUA detection I personally would not recommend disabling it, but you can do what ever you like on your own computer. You might also be a downloading from a less reputable site, even piriform used to use mirror sites for some of their free software versions, I do not know if they still do that. The mirror sites they used were 'clean', but their server security measures are unknown.
Thanks,
- Dave
