Explanation (?):

The alerter service is aimed for use on a corporate/business network. It is used to redirect administrative alerts from the computer the error occurs on to another computer. This is really only useful for domain server environments. Generally speaking the average user will never use this service. Leaving this service set to manual is fine since it only starts if you have a device set to use it. Examples of devices that use it are special hard-disk controllers such as RAIDs or a UPS.

If you are a home user then you can safely disable this service.
