it once happened to me..... a cousin received an email i had sent to my hubby and several people did too........ thankfully it was nothing bad but still, I don´t know how it did that.... we had virus scan the comp and it was clear.....

I didn´t changed my email, but a virus check might be good......

till this day I have no clue what caused it, perhaps a troyan thing that was hidden........ ¿¿??....... now I´m cautios into which emails I open
