What is rootkit
Rootkits are used to hide the presence of a malicious object like Trojans, or Keyloggers on your computer. If a threat uses rootkit technology to hide, it is very hard to find.
Rootkit detectors give you the power to find and delete the rootkit, and to uncover the threat the rootkit is hiding.
If a virus with rootkit functionality makes its way onto your computer, its files and processes will be hidden in Explorer, the Task Manager, and other tools.
Generally, rootkit detectors are capable of the following type of scans, although not all scan or handle rootkits in precisely the same way.
· hidden processes
· hidden threads
· hidden modules
· hidden services
· hidden files
· hidden Alternate Data Streams
· hidden registry keys
· drivers hooking SSDT
· drivers hooking IDT
· drivers hooking IRP calls
· inline hooks
The following are a number of free rootkit detectors available for download.
If you think you might have hidden malware on your system, it’s prudent to run multiple rootkit detectors. Much like anti-spyware, no one program catches everything. Some antivirus software attempt to detect rootkits; others don’t. To be safe, I use each of the rootkit detectors listed below on my machines.
The AVG Anti-rootkit download is a tiny 414kb, and it installes quickly. Its straightforward, no-frills interface allows a regular search and an in-depth search. A standard scan took 12 minutes, while the in-depth search took just over an hour. Neither scan turned up any rootkits.

Great post! These tools will be awesome, I am always afraid of rootkits when I boot in MS, even from files from secure companies. I mean, a security consultant had over 250,000 bots, so who else could be loading trojans into their applications? Thanks again for your post!
