These files can't be opened. Your Internet security settings prevented one or more files from being opened.

OS: Windows 7 Ultimate 32 bit With UAC Disabled

Hi there,

I turned on my computer this morning and suddenly all ____ has broken loose. Every time I try and open an exe file I get a Windows Security alert box telling me that:

"These files can't be opened. Your Internet security settings prevented one or more files from being opened."

I've read through every thread I can find on the topic and none of the "answers" have worked for me.

I have tried the following common "solutions" with no luck:

1) Right click the exe, click Properties
Click the Unblock button
Click OK

2) Adding exe to Control Pannel > Windows Defender > Tools > Options > Excluded file types

3) Start / Control Panel / Internet Options.
(Internet Options control panel appears)
Click "Security" tab.
Click "Local Intranet"
Drag slider to "Low"
Click "Sites" button.
Click "Advanced" button.
Enter the IP Address of the NAS / SMB/ CIFS / whatever server and click "Add."
Click "Close"

4) Remove the registry key -  HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FolderTypes\{EF87B4CB-F2CE-4785-8658-4CA6C63E38C6}\TopViews\{00000000-0000-0000-0000-000000000000}

5) Creating a completely new admin profile. - This one was interesting, when I logged into the account there was no aero theme - it went right back to basics.

So any ideas?
I didn't have the registry entry mentioned in my HKCU. I fixed the problem by resetting all my IE settings. So something in IE is causing it.  That actually fixed the problem for every user profile on the machine.
