Best of luck to you.
I just read something today that said if you have your microphone on and your speakers on and your voice recognition on, someone could send you a sound file that tells the PC to delete all your files and then empty the trash! It can only do what you have permissions for, but if you are like most homeowners, you give yourself full administrator privs. so, very possibly, someone could send out a rogue sound file that tells your machine to make all files visible and then send them all down the dumper. Sweet mother of recycle bins, pray for us!!!
