AntiSnooper is a handy software that helps to protect your privacy by blurring any opened window while working on PC. A particular window is blurred immediately as soon as the mouse cursor is removed from that window. It helps to protect your privacy from prying eyes. It comes in handy when you are chatting on Facebook, filling some confidential data online, or entering password details on some password manager, that you don’t want to be seen by any person.

It automatically shows the list of running applications on its interface and you can select required applications to manage the privacy. For each selected window, you can set blur intensity as well.

Apart from blurring a window, it can run a screensaver within the protected window. To make it more clear, I have created an animated gif visible below.

As you could see in above animation, as soon as mouse cursor is removed, it will either blur that window, or can start running the screensaver.
