Follow the instructions but you might have to alter it to fit the file on your computer...towards the end I got the 'blue screen of death' and was nervous so i shut down the computer and when i restarted it nav's alert wasn't showing up anymore and i can't find the file anymore, where before it was showing and i couldn't get rid of it! i'm scanning to make sure it's completely gone...but using this site is worth a shot since it worked for me!
