I'm on an Apple iMac (intel version) running snow leopard. On feb 16 my yahoo email account was hacked. i found out because i received a mailer.daemon return receipt that an email for a pharmacy that "i" sent out (which i didn't), to everyone of my contacts, couldn't be delivered to some of them. i immediately changed my yahoo password. how did my account get hacked? i thought apples didn't get viruses. or is this a problem on yahoo's side - no one other than me has access to my computer. the day prior i received a weird email from a contact that i'm sure didn't send that said "voice mail from (one of my contacts) i stupidly opened it and it was an mp3 that didn't have a message on it. could i have opened my computer to a virus. thank you for you help.
