I have the same issue, but it always freezes on check 279xx/44151 or somewhere around there. (always Windows.RedirectedHosts) I've had BSOD's with PAGE_FAULT_IN_NONPAGED_AREA (nt4_disp.dll, win32k.sys) errors but reformatting has fixed that. Now I get "Access Violation" errors when it reaches there, or Spybot S+D just shuts itself down.
Then when I restart, i get a dialog saying "This application has been changed since it was created.
Since Spybot-S&D does not change itself, we recommend you check your system for malware and virusses instantly!"
note that my system is clean.
