SOMEONE HAS SENT A PERSONAL E-MAIL TO ONE OF MY MUSIC STUDENTS FROM MY COMPUTER BUT WAS NOT PRESENT IN MY HOME.IT WAS IN MY SENT BOX, AND WAS MARKED WITH A TIME THAT MY COMPUTER WAS OFF LINE. I'M USING A MODEM. NOW I'M NOT CONCERNED WITH THE TIME BECAUSE FOR SOME REASON MY COMPUTER HAS BEEN GIVING ME WRONG TIMES BACK ON MY SENT MAIL SOMETIMES. I WANT TO KNOW HOW TO FIND OUT WHO IS HACKING INTO MY COMPUTER! I HAVE WINDOWS FIREWALL AND AVAST ANTI VIRUS BUT THEY ARE GETTING THROUGH THAT. I JUST WANT TO KNOW AN INEXPENSIVE WAY TO FIND OUT. THANKS! - JJ
