Seems in 2007 there was a real virus.

But the current flurry is a hoax.

Never open an email, if you don't know the person sending, or if the
title is in any way hinky.

I had a friend whose address book was hijacked by a virus and it sent me
a 46K mail with an attachment. Even tho I knew her, it was unlike her to
send something like this...so I deleted it and called her. She was heavily infected and lost files as a result. This was several years ago..the title was some GAME title ..Something Starz or very similar.

Once I examined a header on a no title email, from Yahoo, and it set off my Avast...I almost fell out of my chair! The one blocked that time was a "love" virus. So now I delete all untitled ones too.

You can never be too careful. And now I am VERY careful where I go on the net.
