I have had this problem quite many months now. My Defense+ is quite useless because it lets malware through without restricting or sandboxing it. The files can be found aftrerwars from the trusted files list. And this happens when I test it with proven malware.
I have written about it here in forum but without any help. I have tried to disable other background programs in hope that some of them does something that makes the file seem safe to D+, but without luck.
Now I am waiting for v, 6. with completely new systems.
It has always helpedwhen I have removed all trusted files and the rebooted. D? reacts to some unknown programs and sandboses them. After a couple of minutes usage nothing is sandboxed or restricted.
I can ty something by removing this entry only.
