Several of us have been receiving messages purportedly from eBay notifying us that a message has been sent from a seller. The messages are always the same advising us in the name of some other party that payment has been made or will be made. Note the "keyboard virus" mentioned by eBay security.

I reported this to eBay Security and this is the reply I received:

"Hello,

"Thank you for writing to eBay regarding the email you received.

"We reviewed your report and found that although the message you received
was made to appear as if it had been sent by an eBay user, it was not.
It appears that this email may also contain a keystroke virus. If you
clicked on any of the links in the email, you may have exposed your
computer to this virus."
