My Computer Virus

I ran a virus check and it was OK.  It took awhile to figure it out, James managed to remove all my stuff from my desktop on Joy's iMac and dump it in the TRASH!  Then I made a mistake by emptying out the TRASH into the desktop and I got the spinning wheel of death.  Ariana managed to use her mac remotely and clean my desktop - over 10,000 files I should empty in out once in awhile.
