Panda AntiRootkit is a free utility that performs in-depth scans of your computer in search for hidden resources, identifying and disinfecting known and unknown rootkits. Unlike other rootkit utilities which merely "reveal" hidden objects, Panda AntiRootkit positively identifies known and unknown rootkits and gives the option of removing them, including their associated registry entries, processes and files. In addition Panda AntiRootkit has an Exhaustive Scan Monitor (requires reboot) capable of monitoring drivers and processes loading at boot time. It's unique technology does this at a lower level than any other AntiRootkit utility, therefore revealing all hiding techniques used by the latest generation rootkits. Panda AntiRootkit discovers hidden files, registry entries, drivers, processes, modules, SDT modifications, EAT hooks, modifications to IDT, non-standard INT2E, non-standard SYSENTER, IRP hooks, and much more.
