When testing Comodo against Leaktests such as Comodo's CLT or Spyshelter's Antitest, you should disable Cloud Lookup first or make sure the Rating of the testing executable is Unknown to CIS. For testing again you need to remove the File from File List or change its Rating to Unknown.
Also if you are going to test Comodo HIPS you have to disable Containment, since HIPS does not monitor contained applications.
