>I'm thinking someone should build a (Linux or other *IX) that scans the HD of an infected machine (booted with this distro or the HD was removed and put on another machine) to scan and remove everything.

Also bitdefender: http://download.bitdefender.com/rescue_cd/2013/

and AVG: http://www.avg.com/us-en/download.prd-arl

although I am not sure if they are linux based.
