Frequently, I browse Internet, but the web page change my default
search or home page to other web page. I need to remove them from
registry manualy. If I set the security Level to high, I cannot
visit many pages. Even I enabled PCCillin 2002 firewall, it does
not help.
How Can I protect my registry?
Control access. Lock down IE using Security Zones and options. This
is an IE/OE issue for another group.
Maintain updated A-virus and or other Anti-* tools.
Detect and correct. Various anti- spyware and adware and BHO tools.
Such as Ad-Aware and Spybot Search and Destroy for example. Also

Some utilities to monitor registry changes are available. Both
"snapshot" compare tools and active monitors. Some to be found at
http://lists.gpick.com/pages/Registry_Tools.htm
One "protection" method for the registry is to make full backups of
it periodically so that any massive changes can be rolled back to a
"clean" version. Full registry backups can be made using
ntbackup.exe in the OS or by third-party tools such as ERUNT.
Depending on the User Account and area of the registry, registry
permissions (ACLs) might be used to restrict certain keys. I don't
see this "protection" mechanism as too useful for BHOs or other
writing to HKCU.
