Trend Micro™ RootkitBuster is a free tool that scans hidden files, registry entries, processes, drivers, and the master boot record (MBR) to identify and remove rootkits.

The latest version of Trend Micro RootkitBuster features an even more sensitive detection system.

What It Does

Because they resist detection by security software, rootkits can be hard to remove once they get onto a computer. Trend Micro™ RootkitBuster can find rootkits by checking the following:

  • Master Boot Record (MBR)
  • Files
  • Registry entries
  • Kernel code patches
  • Operating system service hooks
  • File streams
  • Drivers
  • Ports
  • Processes
  • Services

By cleaning or removing hidden files, registry entries, and services, Trend Micro RootkitBuster can eliminate a wide and ever-growing number of rootkit variants.
