according to this page:technet.microsoft.com/en-us/library/ee176961.aspx, Downloaded scripts must be signed by a trusted publisher before they can be run. Maybe you should set policy to Unrestricted temporarily to make this script to run — poiu2000

The ExeutionPolicy RemoteSigned allows running of local scripts(created on your computer) and signed scripts from other locations. Since your scripts is downloaded from the internet, it has a "block"-attribute associated with it.

To fix this, open Properties for the ps1-file, click Unblock and Apply/OK.

Or you could set the executionpolicy to Unrestricted if you want to allow everything(not recommended).

It may be worth mentioning that signed scripts will prompt for confirmation before execution unless you already have the specific publishers certificate installed in Trusted Publishers certificate store.

It's not that strange really. Powershell uses the standard windows rule where executing remote files gives you a warning if they come from untrusted sources(not in Trusted Sites list in Internet Explorer). Opening network files gives you a Run/cancel prompt for the same reason. :-)
