Removing "winfixer"

Symptom: Once a while, an IE pop up window shows up with http://202.67.220.233 in the address field. This pop up window contains a false warning message and advertisements for "WinAntiVirusPro 2006, WinAntiSpyware 2006, and WinFixer 2006". The warning message said:

Attention! Security Center has detected spyware on your PC sending private information and documents to remote computer. One of processes (Win32res.exe) has just sent this information:

Sometime later, another IE window pops up with "http:www.winfixer.com/..." in the address field. The pop up window also contains a false warning message:
