My routine is pretty fixed. Combofix scan followed by Malwarebytes and Spybot Search & Destroy. Supplemental AV scan also recommended.

Usually, Antivirus 2010 is easy enough to remove with either Malwarebytes or Spybot, but where you really have problems is if you have machines that got some bonuses along with AV2010. Neither Malwarebytes or Spybot are effective against most common Virtumondo.H variants.

Also, I've seen a recent increase in bugs that will either block most malware removers, or sleep and then reinstall. So, you should probably make it a point to rename the executables before using them.
