Avira Antivirus (FREE AND PAID VERSIONS)
This AV has been around a long while, though it's not extremely popular. Not as good as it used to be, but still does a decent job.
Kaspersky Antivirus ($$ NOT FREE $$)
Kaspersky is one of the more known AVs that also does a great job at detecting the bad stuff. Kaspersky has been improving a lot over the past few years and has gained a lot of respect from a lot of security minded people. It, however, does not have a free solution. In the past a vulnerability was discovered in the Kaspersky product that actually reduced the security of the system that was running it, but this issue has been resolved and it is now a strong, solid product.

Rootkits are common in the wild, now. What the hell is a rootkit? Please see this article on Wikipedia. A lot of viruses and other malware are starting to include them in their payload so that they can hide from detection tools. Most AVs, including Kaspersky and Avira, are now offering some sort of rootkit protection and detection, but it's better to have a second, third, fourth, and maybe a fifth or sixth opinion when it comes to detecting them. Here's a few good tools for doing just that. Not all, maybe not any, of them will detect all rootkits. You may need to run a few of these tools to make sure you find everything. Please note, that these tools are fairly advanced. Just because they output something, doesn't necessarily mean you have a harmful rootkit on your system. You may have to research the output a bit to confirm or dismiss the "detection". You also may have to boot to a third-party live-cd like Ubuntu to remove them successfully. It may be better to let a shop clean it up if you have no idea what I'm talking about. NOTE: Some software legitimately use rootkit technology in their software for good reasons. EG: An AV may hide portions of it's software so that malware will not notice it on the system.
WARNING: These tools WILL produce false positives! Be careful!

Hitman PRO 3.5 - 30-day trial. Great at detecting malware and rootkits. However, I would only run the software in portable mode, because it is buggy if you leave it running resident. It can crash explorer if you install it to your system. It's best used as a standalone cleaning tool.
Radix Anti-Rootkit (32-bit only)- Nice, free, GUI (graphical) anti-rootkit package.
Kaspersky TDSS Removal Tool - TDSS is a family of rootkits that a lot of Rogue Antivirus software has been using to do their dirty work. This is a removal tool created by Kaspersky that can be used to remove it.

Dr. Web CureIT ADDED 7/2011 - Not sure how I forgot to include this great little tool. It's particularly great at disinfecting files that have been patched and removing full blown viruses. I recommend running this tool initially when performing a cleanup operation.
These tools are very good at getting rid of malware that just will not go away. They are considered a last resort, but they usually work fairly well. Do note, though, that using them incorrectly could cause you to have an un-bootable system. They might delete system files if they detect malicious code embeded in them. In order to restore the system after this has occurred, you will have to have access to an OS installation disc, and you extract the system files from the disc and then copy them back over to the correct location on the computer using a third-party bootable live-cd. Sometimes a complete Windows XP/Vista/7 re-install may be required.... or just easier.
Combofix - Taking from it's website: "ComboFix allows the manual removal of spyware infections . It 's a specialized effective cleaning tool, which is useful compared to other malware and spyware removers.
After Combofix finished,a report will be created. You can use this report to search and remove infections which are not automatically removed." This program updates occasionally, so be sure to update your copy.

It is a very strong tool that shows everything you need to know about applications that auto start when you turn your computer on. Can be used to prevent running trojans and other malware on startup.

CCleaner - CCleaner (aka Crap Cleaner) can clean out temporary files and other "crap" on your system.
CleanAfterMe - This is a very nice registry and temporary file cleaning tool. Any cleaning this tool performs will not break your system, which is sometimes not the truth of other registry tools. Make sure you uncheck "Installed USB Devices" or you may have to unplug and plug back in all of your USB devices to get them to work again.
CurrPorts - This tool can be used to determine if any open ports exist on your system. Sometimes malware may open a backdoor to your system and make you apart of a botnet so that your computer can be used to orchestrate other attacks. This can be used to to see what ports are open so that you can research it to see if they are known to host any sort of malicious server. Note: Rootkits can hide port information, so this isn't going to be effective 100% of the time.

EXEFix for Vista - Repairs the registry so that EXEs will run on Vista. <<not uploaded yet>>

FileAssassin - Brought to you by the developers of Malwarebytes, this tool can be used to delete files when a normal delete just doesn't do it.
HiJackThis - Tool used to find BHOs, start-ups, browser addons, registry entries, and strange files on your system. HiJackThis only gives a report of what's on your system. It's not going to tell you what's bad and what's good. You have to determine this yourself. For this reason, you can post HiJackThis logs on Internet forums if you need help deciphering the results. Bleepingcomputer is a good place to post these logs.
