15 AntiRootkits to Detect and Remove Malware that Uses Rootkit Technology


Malware that uses rootkit technology are the worst because they are hardest to detect and can even stay infected on a machine for years without being discovered. Here we put 15 dedicated antirootkit applications to the test to see the effectiveness of these programs.

There are many different types of computer malware and the ones that use rootkit technologies are the worst because they are hardest to detect and remove. Rootkit technology is able to hide its presence from the most basic tools built into Windows such as Task Manager, to your most trusted firewall or antivirus software and you won’t even know that it’s there. This is achieved through installing and loading kernel-mode drivers which can allow the malware to run with higher privileges.
Although 64-bit Windows operating systems are generally safe from rootkit infection because by default the operating system only accepts signed driver files, there were previous cases where legitimate digital certificates were stolen by hackers and used to sign rootkit drivers to bypass security software and Windows defenses. Antivirus software was not much of a help either because the Stuxnet worm successfully stayed infected on the computers for years before it was discovered by VirusBlokAda, the developer of VBA32 antivirus software.
Since antivirus software are far from being perfect in catching rootkits, we’ve put 15 dedicated anti-rootkit tools to the test and see if they are able to detect the 3 different keyloggers (All In One Keylogger, Invisible KeyLogger Stealth, Elite Keylogger) that uses rootkit technology which we have installed on our test system.
 1. avast! ANTIROOTKIT

This free and portable anti rootkit tool by avast! is outdated and no longer being maintained since 2008 because it has been integrated into their antivirus program but can still be downloaded directly from their server. Using rootkit detection technology based on GMER, avast! ANTIROOTKIT only managed to detect All In One Keylogger while missing the other two driver-based rootkit keyloggers. Clicking the “Fix Now!” button successfully deleted the files after a restart.

 2. AVG Anti-Rootkit


 This free anti-rootkit tool by AVG suffers the same fate as avast! because it has been abandoned since 2006 due to the integration of this anti-rootkit into their antivirus software. The program requires installation, a reboot and either manually run as admin or disable UAC to run. The result of AVG Anti-Rootkit is also the same as avast! where only All In One Keylogger is detected while missing Elite Keylogger and Invisible KeyLogger Stealth. The “Remove selected items” button does not delete the infected files but replaces the last character of the file’s extension with an underscore, for example from .exe to .ex_

 3. Bitdefender Removal Tool / Rootkit Remover

 We weren’t able to determine the if Bitdefender’s antirootkit tool is called “Removal Tool” or “Rootkit Remover” because the program’s name and website says differently when they are the exact same application. Bitdefender Removal Tool is free, portable and up-to-date (last update on February 2013) but can only detect known rootkits through signatures and not the undetected ones. The scan takes merely a second to tell you if there are any rootkit threats detected. Both 32-bit and 64-bit versions available. Bitdefender Rootkit Remover fail to detect all 3 rootkit keyloggers.
