[What is Service: Network DDE NetDDEFastUserSwitchingCompatibility]

Hi, I have been working with SpyBot S&D team to clean my computer of some nasties, all the logs are now showing clean and the tech helping me feels comfortable about everything except for one thing and he has asked me to post here to see if anyone on this forum would know what it is.

Service: Network DDE NetDDEFastUserSwitchingCompatibility

I do have multiple users on this computer and I have gone in and unchecked the Fast User Switch box but the above still shows in the logs. We just want to make sure that this is not something that should not be on my computer.

Any help would be most appreciated.

Thank you,
Cindy
