I opened an attatchment sent to me by my Uncle. It was from a Canadian Paharmacy advertising Viagra. I replied to my Uncle that since I am his NIECE I probably wouldn't use it. He replied that someone had gotten into his address book and sent that add to everyone. Tonight the same add was sent out from my address book to all of my contacts. I just spoke to my son that knows a lot about computers and he told me he has had that same complaint today from numerous people.
