[edit] Lists of freeware antirootkit

Currently (2006-2007), rootkits are the number 1 threat on most people's horizons. Surprisingly, most of the current offerings that specifically target rootkits are freeware or open source.

[edit] Memory resident antirootkit

1. AVZGuard - http://z-oleg.com/secur/avz/download.php (second download on the right avz4en.zip is English)
2. Helios - http://helios.miel-labs.com/ Helios Lite does not require installation
3. GMER - http://www.gmer.net/files.php
4. See also Lists of freeware behavior blockers

These are antirootkits that claim to have a resident shield component. Not very common, and unlikely to be very different from HIPS

[edit] On demand antirootkit scanners

[edit] Standalone scanners by conventional AV companies

1. AVG Anti-Rootkit Free - http://www.grisoft.com/doc/download-free-anti-rootkit/us/crp/0
2. Avira AntiRootkit Tool - http://dl.antivir.de/down/windows/antivir_rootkit.zip
3. BitDefender Rootkit Uncover - http://www.majorgeeks.com/download.php?det=5157
4. F-Secure BlackLight (beta) - http://www.f-secure.com/blacklight/
5. McAfee Rootkit Detective - http://www.majorgeeks.com/download5447.html
6. Panda Anti-Rootkit - http://research.pandasoftware.com/blogs/research/archive/2007/04/27/New-Panda-Anti_2D00_Rootkit-_2D00_-Version-1.07.aspx
7. Rootkit Buster (Trend Micro) - http://www.trendmicro.com/download/rbuster.asp
8. Sophos Anti-Rootkit - http://www.sophos.com/products/free-tools/sophos-anti-rootkit.html

Most of these stand alone anti-rootkit released by AV companies are relatively new (BlackLight is the oldest). Many will eventually be incorporated into future products to extend anti-rootkit abilities. Avira AntiRootkit Tool is already built into Antivir. Because they have being slower to the game compared to independent developers (see next section), they are probably not very effective.

[edit] Relatively well known and popular antirootkits

1. DarkSpy - http://www.fyyre.net/~cardmagic/index_en.html
2. GMER - http://www.gmer.net/files.php Mirrorsite - http://www.majorgeeks.com/GMER_d5198.html
3. Radix - http://www.usec.at/
4. IceSword - http://www.antirootkit.com/software/IceSword.htm and IceSword 1.2 for Vista
5. RootkitRevealer - http://www.microsoft.com/technet/sysinternals/utilities/RootkitRevealer.mspx
6. Rootkit Unhooker - http://rkunhooker1. narod.ru/
7. System Virginity Verifier - http://invisiblethings.org/tools.html

These are rootkit scanners released by independent (none-AV) developers. RootkitRevealer was the original anti-rootkit that sparked off the recent arm's race in this area. IceSword and DarkSpy (both from China) are excellent but development has slowed. GMER and Rootkit Unhooker are cutting edge tools that are still being developed rapidly.

Note: While some of the anti-rootkit tools above are by well known developers (RootkitRevealer and System Virginity Verifier comes to mind) , others are by developers who have chosen to remain anonymous (or semi-anonymous), so there might be some suspicion . However the tools listed in this section are well known and have received quite a lot of scrutiny so they are unlikely to be malicious. Be wary of downloading any new anti-rootkit tool or claimed new version from unknown sources though.
