Yahoo and other providers were hacked of information: Meaning that the info was not taken from individual computers.
My Yahoo account information was hacked...Sorry
Apparently it was sent out with HEY name..Have you seen this and a bogus MSNBC link. an bogus MSNBC link.
I keep an updated Security suite on my computer and it did not help on this one. Funny, I had just run the update when i logged on.
The bogus was an outside attempt using data from the Yahoo files on their servers, and maybe other providers.
