Don't know if this is just a furphy or not, but a mate here has warned me that over the next few weeks, because of the anniversary of 9/11, to beware of e-mails, (even from people on your lists ), that contain anything relating to the World Trade Centre.
Especially anything marked WTC Survivor, as this wil delete all your .dll files.
Even if this is bullshit, it pays to be prepared.
