And I cann't remove the unused computers in CPU subpage
wreck_P4HS Intel Celeron 1.70GHz
Windows,v25.7,build 3 1693 2008-Nov-3 09:40 ‡ [has not been seen for 90 days] T 0.0 TF

v4_computers 2008-Oct-30 02:10 ‡ [has not been seen for 90 days] U 0.4
Is these computers are too old to remove or some else wrong?
I use Firefox 27.0.1
