Try putting the Kindle in airplane mode, deleting the entire acw folder, then rebooting your Kindle.
Nothing tragic should happen, and the files there should be populated again the next time the Kindle connects to Amazon (see the timestamps in the files? From all that I know, they're sort of "mini-updates" of some functionality, which can be updated independently from the base OS).
If none of that helps, I guess your only option is a factory reset.
PS: That http___kindle.amazon.com_ns_widgets_EndActions_3.0 .2-endactions-et-3-20130625161444.acx file sure looks odd... maybe try deleting only that one first.
