Apenas percebi que deixei essa questão aberta pendurada. FWIW, acabei encontrando a melhor explicação em Como -To Geek - O que é o Mobsync.exe e por que ele está sendo executado? . Citação:
Mobsync.exe is a process that belongs to Microsoft Sync Center and the Offline Files feature. It’s associated with a device like a Windows Mobile phone with ActiveSync, a SQL Server installation, or if you have Internet Explorer (a feature in IE 6 not in IE7 or above) set to synchronize pages for viewing offline. The process is not a threat and shouldn’t be deleted if you’re using the feature. If you go into Control Panel, you can launch Sync Center and manage its settings.
Em termos de desativação, o artigo continua:
