What is ehmsas.exe?
This is the Microsoft eHome Windows Media Center State Aggregator Service. It is installed as part of Windows XP Media Center Edition and the versions of Windows Vista that support Media Center functionality. Its purpose is to keep track of media files for Media Center.

This process is not essential to the operation of the system; however, it is essential to the proper operation of Media Center. Disabling this program will cause Media Center to crash or lose track of your media files. Deleting this program may result in system instability.

Dangers of ehmsas
As this is a legitimate executable that is installed on any version of Windows with media center functionality, it is common for virus writers and spyware vendors to disguise their malware as the genuine one.

Some malicious files may have the same name as this process but be stored somewhere other than in %SystemRoot%\eHome. Other malware may use a name that appears similar to that of the legitimate one but with slight differences in spelling or with appended digits. While there are currently no known viruses, Trojans, or adware applications that disguise themselves as this process, you should look out for the presence of this file in an incorrect location or with a slightly different name.

There is typically only one instance of ehmsas.exe running at a given time on a system. The presence of multiple instances may be an indicator of a malware infection. If you do not have a Media Center-capable version of Windows installed, the presence of this executable is a likely sign of a virus infection.
