Strange Issue

The Defense+ Module says that mshta.exe is a unsafe Application but when I sumbit it the firewall calls it safe.What is going on? Here is my Specs: Operating System Information
========= ====== ===========
Operating System : Windows XP
Operating System Version : 05.01.2600
Service Pack : Service Pack 3
Internet Explorer Version : 7.0.5730.11

Hardware Information
======== ===========
Central Processing Unit (CPU) : Intel(R) Celeron(R) CPU 1.70GHz
Available Memory : 205MB
Total Memory : 502MB

The firewall doesn’t call it safe or trusted. You need to input that.

Oh thank you and I meant it was on the safe list but Defense+ considers it unsafe. Sorry about the mix-up.
