Thor wrote about IconHandler starting mstask. Are there any other dangerous IconHandler entries: is there a way we can reassure ourselves that the others are safe? Being curious, on Win2k, I copied cmd.exe (from winnt\system32) as xyz.pif; then (right-click) Properties, Program crashes explorer. Is this related to IconHandler, and is it exploitable?
