Sorry if this is nto right forum for it.
I have just download the latest WordPress version 3.5 and CA (my anti-virus) advises me that there is a Trojan in the Twenty Eleven header image/trolley.jpg
The threat is reported as PHP/Obfus.F
This applies to both downloads .zp and gz.
I checked all previeous downloads i.e. v3.42, 3.41.,3.3.1 etc and they are fine.
As such I thought to report it just in case. My apologies if I am wrong.
