Recently I got Windows 7 and was downloading some old games. One, Pacific Storm, would not load and needed something called sm.exe. Looked on the web and found that sm.exe was not part of windows, no one was quite sure what it did and its country of origin was China. But, more alarmingly I found links to a site where i could download it. If you come across this file, do your own research before you put it on your computer. I like 7, but after all these years on windows 98 and XP, it takes some getting used to.
