By doing a fresh install of Vista, you would have wiped all entries that
existed in the Restricted Sites security zone. IE8 is known to get slow
when there are thousands of sites listed under the Restricted Sites
security zone. The cure is to clean out this list and only add the few
sites that you actually visit and want to thoroughly neuter (and let the
new security features in IE8 handle the rest).
Several security programs will insert thousands of entries into the
Restricted Sites security zone. SpywareBlaster and Spybot S&D are just
a couple of them. If you don't still have these utilities (to use them
to remove all their entries but which is sometimes incomplete), you'll
find manual removal is tedious using IE's dialogs. You can remove the
registry keys more quickly but many folks are fearful of putzing with
the registry. You can save:
to a file, right-click on it, and select Install. This will make
registry changes to delete the ZoneMap entries and recreate them (but
empty). ALL sites in every security zone are deleted. If you have
entries in the Trusted Sites zone, record them before deletion.
