RegDefend is a kernel based registry protection system, designed to use as few resources as possible.

RegDefend comes preconfigured to protect the most vulnerable areas of your registry, only alerting you when something important is about to be modified or deleted.

RegDefend is a part of the Ghost Security Suite, a unique system designed to minimize resource usage and eliminate wasteful programming methods.

Real customer opinions!

"With the alerts RegDefend gives me when programs (or bugs) try to edit the registry, I have full control of whether they are allowed to or not. Having this type of control has saved me from having viruses and spyware from embedding themselves in my registry. If you are looking for the ultimate computer security (which is also light on computer resources) you cannot do any better than RegDefend and AppDefend."

"I can't list how many times Ghost Security products have helped us track down problems on errant machines at our workplace, well worth the small investment."

"I just wanted to take a moment to write and thank you for your new program Appdefend. I have come to appreciate how much your first program Regdefend protects the registry from software making changes in critical areas without my knowledge. Appdefend extends that protection, by an order of magnitude, by extending that protection to applications on my system."
