Registry Guard v1.9

Registry Guard is a powerful utility which uses a kernel-mode driver to prevent any process or only specific processes from writing/reading/deleting custom registry keys/values. You can prevent, for example, any process from writing to registry autostart locations, or prevent processes from hijacking your Internet Explorer registry settings, and much more. With Registry Guard you can easily protect custom Windows registry keys and values from unauthorized modifications or deletions, a swiss army knife against nasty malware and trojans.
