Recently I've been receiving an error message when I log on to my desktop which reads "Windows is unable to find SMSSuc.exe." I don't know where it came from or what it is, but it seems to be slowing down my log-on time to about a minute as well as possibly affecting other programs on my computer. A web search for this file name brings up nothing. My son also uses this computer for heavy gaming, and it might possibly related to something of that nature, though he has no idea what it is. Does anyone know what this might be, and how to resolve it? Thanks.

1st step , run a virus check from 1 or all of these .

Thanks for your help, Johnw. I tried running a couple of the applications on your list, but those people are all too nosy and want all my personal info and/or they wouldn't install on my system because I'm not a network server. Anyway, I got Stop-Sign to install relatively painlessly and ran the scan. It identified a couple of "possible threats" (an extremely vague term as far as I'm concerned). At this point, I wasn't so much interested in DELETING the problem as I was in IDENTIFYING what this rogue "SMSSuc.exe" file was. But, I held my breath and crossed my fingers and went through with the delete. (Incidentally, I had to MANUALLY delete the files, since I wasn't about to subscribe to ANOTHER detection program.) The punch line is that I don't know if any of these Stop-Sign-detected files were the problem, because immediately afterwards, I ran Adaware (which detected a number of spyware entries that weren't there 3 days ago, the last time I ran it- DAMN! those things are sneaky!) and deleted those problem files as well. When I rebooted, my desktop screen came right up, the error message was gone, and things are running a lot better. Thanks again, if it was your suggestion that helped.
