when I try to download an EXE from IE8 I get 'Your current security settings do not allow this file to be downloaded'
'enable download' is checked in security.
when I try to download an EXE from firefox it allows me to click save file but then the file mysteriously cancels with no explanation
This is affecting 5 users the same way. 4 using Windows 7, one using Vista.
Also, suddenly when we want to install a program that was previously downloaded from the internet we first have to click properties and click 'unblock'
No group policies were changed recently.
