While working with "wininet", I ran across a new feature. In the user temp file (C:\Users\(UserID)\AppData\Local\Temp\) I found a directory called "SmartScreen" with a sub directory called "RemoteData". In that directory were 3 files:

The last file contained:

A quick search reveals that SmartScreen is a relatively new Windows feature that is supposed to warn you if you attempt to visit a questionable web site. It operates in the background, with some conflicting opinions on its usefulness. Personally, I have found no discernible delays or negative impacts and have yet to see a warning.

Opinions?
