Cannot run .exe files

Hello,

Since yesterday I have been unable to open any .exe programs on my Windows 7 computer. I have read numerous questions and possible solutions for this, but none has worked.

I get an error window saying:
These files can't be opened
Your internet security settings prevented one or more files from being opened

I have read about editing the registry but it hasn't worked. I cannot restore Windows 7, as I have found out I have no restore points (oops).

I have run a full scan of my system with MS Security Essentials, and found nothing.

Can anyone help? If you need more details, let me know.

Additional info:
- I cannot for example open notepad.exe. But I can open a txt file and it will open in notepad.
- Same goes for firefox, IE and Opera. Can't open the browsers directly, but if I run an html file and choose "Open with" it will open in the desired browser.
- My MS Security Essentials doesn't run on startup (non of my startup programs do), but I can right-click a file and choose to scan it with MSSE and it will open and scan.

I don't remember the exact problems anymore. There was one registry ploblem, but it looked like it was a false/positive.

Anyway I re-installed Windows and I'm now getting everything back to the way they were.
