After installing this piece of software, my internal clock changed multiple years and my time was impossible to reset, I currently reside in Dubai if to believe my Windows clock. I am a true jetsetter as my timezone change by random all the time! If that wasn't annoying enough, the software doesn't work efficiently at all, it's nearly impossible to block programs. Oh yeah, it took me more than an hour to figure out how to uninstall it. And no, Add/Remove programs isn't enough, and there is no uninstall program and the folder is hidden. Wonderful waste of time.
