AntiRootkits to Detect and Remove Malware that Uses Rootkit Technology:
-----------------------------------------------------------------------
 
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.
