From Panda Security:
Panda Anti-Rootkit shows hidden system resources, identifying known and unknown rootkits. It analizes hidden drivers, processes, modules, files, registry entries, SDT modifications, EAT hooks, modification to the IDT, non standard INT2E and SYSENTER, IRP hooks. Unlike other anti-rootkit utilities which merely "reveal" hidden objects, Panda Anti-Rootkit positively identifies known and unknown rootkits and gives the option of removing them, including their associated registry entries, processes and files.
What's new in this version:
This version is the first release on CNET Download.com.
Ran at boot time and it bluescreened. Had to go into safe mode and disable phooks.sys. I found out it had deleted all my system Restore files. I thought that I'd remove it manually but it starts in the files that Windows uses to boot.
You could use it on the computer of someone you hate but i suggest you run away from this nightmare and be afraid, very afraid .
I am surprised that it seems to detect things that most other rootkit removers do not find and seems to clean them nicely. It found a bunch of critical system files with Rootkits and removed them without a problem.
I have heard that it knows about existing rootkits but it seldom gives me a name other then unknown rootkit.
Completely destabilized my system. Running XP, and the system would boot, but I couldn't enter my profile w/o immediate automatic system reboot. Had to enter different profile and delete the Panda EXE. Still not sure I have everything returned to normal. Highly recommend that you stay away from this product.
It's free, doesn't need to be installed and runs quickly and easily.
Nothing that I can see.
richie58 says it didn't work. I had an almost certain root-kit grabbing my computer and when I ran Panda ARK, it behaved as richie58 describes. I reinstalled XP and no problems - Panda ARK ran. I suspect the root-kit prevented Panda from working, but any geeks out there please correct me.
It's a zip folder app so it doesn't install anything permanent on your drive except the zip folder of course.
Could not complete a scan. (See Summary)
I kept getting a pop up message that there is an error and the app needs to close. Thinking there might be a compatibility problem with one of my other security apps I disabled all of them including the firewall, then ran a scan with the same results. I would get to 17% of the registry scanned and get the pop up. OS: Windows XP Professional SP3

Since I couldn't get the Panda software to work I installed F-Secure Blacklight Rootkit Eliminator 2.2 to do the same job with no freezing hassles. You can download it at F-Secure's web site.
A few weeks ago, after I ran it like I normally have for the past year and a 1/2, it'd scan the first category, then it'd go to the 2nd and after a few seconds I get an error from Windows saying that PAVARK.exe had encountered an error or something.
I liked it while it ran but now that it doesn't, I have to say it's not worth it until they fix it.
