Just a "heads up"... the Wise Disk Cleaner app has a button on the main toolbar that, when pressed, loads up a site that seemed rather questionable. It was some sort of site in which the visitor would pay money to get answers to unrelated topics.
It seemed questionable, so I immediately uninstalled Wise Disk Cleaner... which was super easy due to the excellent Portable Apps Platform! (Thank you!)
Anyways, it's just a heads up. I didn't try the other "Wise" apps to see if they did the same sort of thing, but it wouldn't be a surprise if they did.
