I have an external hard drive that I use to back up my system. I have
recently been attacked by two trojans (despite all the programmes that I have
which should have prevented them). Ihave now cleared them out and want to
back up my new cleaned system. The Windows back up will not complete as it
says the System state is incomplete. Exact message here:
Error: Could not access portions of directory System State\COM+ Class
Registration Database.
You may not have permission to open the file, or the directory may be
missing or damaged.
Please contact the owner or administrator.

Error: Could not access portions of directory System State\Registry.
You may not have permission to open the file, or the directory may be
missing or damaged.
