Warning: defense + module isn't working properly

I keep getting a warning saying my defense + module is not working properly. The diagnosis of the software comes up with nothing. But it doesn’t say what to do next, so what to do, because this has returned now. Please excuse my English, the jargon is difficult. Also, I read on the forum that Comodo keeps not recognizing Avast. I have the same problem. Thanks for helping out.

I have the same problem. I also have avast.
1 Is the combination a problem? Is this what is causing the warning?
2 Despite the warning, is it functioning or not? ???

Please someone HELP!

I don’t know which OS and version of Avast you have. But I can tell you that Avast 6.1 and Comodo FW & Def+ work together without problem on Win XP SP3.
