What was the file name, location and malware name of the detection ?
Not sure what security report you are talking about, was it the one shown in the More Info button of the avast alert window ?
The default action is to move the detection to the avast chest, that may differ depending on the shield that detected it. That is why the above question is relevant.
I trust that you have uninstalled the Trend antivirus (?) or this could conflict with avast potentially leaving you less well protected.
