I came across that incomprehensible multi-pageful of scripts too.

So [whatever put it on there] appears to be using this Beastware-spawned java aplet (?) as a repository
-- but for What?
Even typing in ".micro....." so that there's only that one entry on page, then 'Erase All' - gets it to disappear

Methinks this thing Shouldn't Be allowed-to-stay.. if it ain't MyWare, it's MalWare.
Considered reloading Safari from current Apps copy, but have to ensure that History shall not then become, er, History. Then on to Root Kit Revealer (via whatever incarnation for OS X.)

Oh well, forces me to improvise..

Edit:

(Though unclear why a reload *should* tamper with stored cookies..)

Duh. try the obvious next time -- earlier.
