Killer, have you succesfully "uninstalled it"? Or it won't go away?
TAG, and anybody else who got this...IF Killer did, in fact get rid of it, try deleting your cookies. Sometimes spam like this 'stings' your computer so-to-speak in the way of cookies. If the 'stinger' is gone, the spamware won't know where to find you.
And Killer, I suggest you report this thing to Myspace admins...NOT good for the site if this is happening to other people, and just maybe they have a 'cure'.....
