hi i have xp prof sp3 (freshly repaired) but the problem happens after a
trojan raid my pc.
if i try to start the automatic update service or the intelligent background
transmission service. it tells me no file found.
so no manual update via ms webpage.
if i look in update.log some veresion seems too low.
