In 8.7i, the process MFEAnn.exe is a child process to McShield.exe.
If you have multiple MFEAnn.exe processes, it means that McShield.exe must have encountered some issue to cause it to restart - and then most likely, the "older" MFEAnn.exe has become confused and is possibly trying to connect frantically to the older instance of McShield that no longer exists.
Since that scenario is fueled by McShield restarting - and again, most likely due to a fatal scan timeout occurring - you might want to consider upgrading to a later release where timeouts are less frequent. If that means 8.7i P5, you'll still want HF 638179 which is available from the knowledgebase.
Ideally, you'd go to VSE 8.8 Patch 2... just as soon as it's available, as it has no need for any timeout-related hotfixes.
