I got an email with no subject and the sender doesn't appear?

There is a way of seeing what's inside the e-mail without opening it. I strongly recommend that you do not open it, especially if it has an attachment.

For information on reading an e-mail without opening it:

Don't open it because it's most likely spyware, adware, a virus, or just regular old spam. If you're really curious the only thing that I would suggest is if you can scan the email before opening it for viruses and it comes up clean then you might want to try it but I'm sure if it was your friend it would show her email address.

Sure, it can. Don't ever open anything unless you know the sender. Don't even open something that has an interesting subject. These can be very dangerous.

omg.......don't open it.......its a virus.......i have 3 computers and there on a network.........and after i opened a email with no sender or message they started running very very slow. hope u didn't make the same mistake i did.

it's a virus! never open it when the sender area is blank.

Its just spam E-mail don't open it

Just mark it as spam And yahoo will flag it - so it will goto you spam E-mail folder the next time ( everyone get an E-mail like that )

i also got one the other day, its a virus, so do not open it and delete it.

DONT OPEN IT....virus.trust me
