sfsync02 seems to be a Starforce driver (used for protecting games against copyright). Their website has a tool that can be used to update (this might fix the driver and therefore solve the issue) or remove the feature. Removing it should solve the issue but may mean that you cannot use the programs that rely on Starforce, reinstalling the programs could fix this, but I'm not sure. I would say try the upgrade tool and then if that doesn't work remove the driver. Click here for the link to their website.
