The rootkit detection tools out there right now seem to break down into two basic categories:
- Professionally written tools, which seem to be mostly marketed as a way to get people to buy a full commercial product.
- Independently authored tools of broadly varying pedigrees and usability.
If rootkits continue to proliferate and become as difficult to detect as is predicted to happen, that will be yet another selling point for the major security-software makers to market their own products. But it also will be an incentive for the indies to continue to write and update their tools for their own market, too.
