Its how I think Yahoo got forced down for a few hours, since a special file was sent out with e-mails to force the server down.
Correct,a while back, I was infected with a Trojan, I opened an e-mail showing the name of a friend as the sender, & immediately a notice flashed up telling me that I was infected with Trojan dropper virus, followed by the specification.
Since I got a better AV, there have been more, but they were contained in the AV's vault.
I understand that the sender's address was extracted from my address book.
