Windows 8 is meant to be used by people who don't know much about computers. Thus, the approach they take might not fit skilled users.

Ideally the novice user will take their machine to a clueful technician who will wipe the drives and reinstall the OS, and then offer to set up firewalls and anti virus software.

Unfortunately novice users often do not back up their data so wiping the drive is unpopular.

And there are many technicians who think that malware removal without wiping the drives is acceptable.
