In the last 24 hours I have received emails from folk I know directing me to different wp sites. My friends did not send the emails (their emails were hacked!)but I recognized the impossibility of the addresses as a wp user. The sites were strep throat treatments and http://emergencysiracusa.dotcoma.org. Both emails directed me to a page in /wp-content/themes/.....
I suspect a trojan was lurking
For general info
