Hi
Of course you can post here in our “small” Toshiba European forum even you are from US.
But the point is that your issue has nothing to do with Toshiba but with your 3rd party software: Trend Micro Security firewall
I doubt that there are many users who would be able to help you but I recommend searching and contacting the guys from Trend Micro support:
Check this

I think you will find some useful hints and tips.
Cheers
