Free Online Independent Malware Scans

Try a couple of these free, online scanners to see if anything has slipped by your protection (most require that you use Internet Explorer):
(Be advised that some of these scanners will pickup things in "quarantine" from other anti-virus programs - so review the results carefully
Having difficulty with running the scans using IE9? - some scans are being updated by the manufacturer - thanks to Tehsplink!  added 17 Feb 09 - thanks to Tehsplink!  added 17 Feb 09 - Scan Only, no removal - Scan Only, no removal

If you find that you're infected (or the scan doesn't complete or closes unexpectedly), post in the malware/security forum
If you're not infected, post back in the original location and we'll try some more stuff.

TDSS Killer:
Be very, very careful with this.  The TDSS rootkit infects the partition table - so even a full format won't remove it.  When using a tool like TDSS Killer a very real possibility exists that the system may not be able to boot afterwards.  If unsure, ask for additional advice about using this tool.  FYI - I am not a malware removal expert, so I don't presume to be able to offer malware removal advice.  I'm experienced enough that I can offer advice for recovering from a damaged partition table that won't let your system boot.

Power Tools:
BE VERY, VERY CAREFUL!!!  These tools can hose (damage) your system if used too aggressively!!! 
Set a System Restore Point before using!!!
- Norton Power Eraser (requires internet access to operate):
- Microsoft Safety Scanner (haven't used this myself):

- Comodo Cleaning Essentials (has "KillSwitch" - a Process Explorer w/whitelist for processes):
