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

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