Changed my mind on quietzone. I decided to uninstall it because of some compatibility came up but to my surprise I found it has no uninstall option. I tried several uninstall tool like revo, iobit and windows and ccleaner and all show no sign of quietzone in the installation list. So now to my horror I found there is no way to uninstall this software. I was forced to search the pc and edit the registry manually and with registry cleaners to clean quietzone. After a long cleaning procedure, I still fell traces maybe left. I could not find any uninstalling info online and the re-downloading the program and running does nothing but update current install. So this is a warning for anyone using this software.
