Buyer beware, AyRecovery and PerfectUninstaller softwares on Windows 7, once you installed it, you can't remove it, it's own uninstaller doesn't work, neither windows uninstaller, instead they promote another of their own product by name, PerfectUninstaller as a solution. This is a sleazy business practice, create a none existing problem, and trying to sell you a solution, the sad part is even their own solution doesn't work. The web is full of solution, guess who is behind all the bogus solution, they are.
