SmartScreen Filter checks the files that you download against a list of files that are well known and  downloaded by many Internet Explorer users. Unfortunately because Tracker is not currently on that list,  SmartScreen Filter will warn you.

The first screen requires the user to click “More info” and the second screen requires the user to click  “Run anyway”. Tracker will not install if you only click "OK".

If you click "More info" you will be presented with the option to click “run anyway” to install Tracker.

One option to prevent this from happening with Tracker or any other programs is to disable Windows SmartScreen Filter.

How do I turn SmartScreen Filter off or on?

1. Open Internet Explorer by clicking the Startbutton . In the search box, type Internet Explorer, and then, in the list of results, click Internet Explorer.

2. Click the Safety button, point to SmartScreen Filter, and then click either Turn Off SmartScreen Filter or Turn On SmartScreen Filter.

3. In the Microsoft SmartScreen Filter dialog box, click OK.
