Registering a VB6 dll seems to fix missing agents:
1) Open up a command prompt (stªrt -> run -> cmd)
2) Type in the following "regsvr32 msvbvm60.dll" (without
the quotes).
3) Close and re-open Windows AntiSpyware
4) If that fails, install VB6 runtime files: http://www.softwarepatch.com/windows/vbrun6downlºad.htm
