Our office just installed a new computer and imaging system, which includes viewing scanned tif images through an Internet Explorer browser window. When anybody clicks on a link to "view" a particular tif image, a window with the title "File Download" always opens. The text of the window says "Some files can harm your computer. If the information below looks suspicious, or you do not fully trust the source, do not open or save this file" Then, below there are buttons to Open, Save, Cancel, or More Info. Since this office views a LOT of images, it is a non-productive nuisance to have to confront this window every time somebody wants to view/open a tif image.
A little research has indicated that there is a file called shdocvw.dll which contains a list of file extensions which trigger this window to open. Tif file type WAS NOT ON THIS list though. I'd like to know two things: Why is the tif file type triggering this security window to open and even more importantly, what can I do to prevent this security warning window from opening?
