Occasionally event ID 1000 source 100 is caused by DEP. DEP or data execution protection prvents applications (and virus) from launching in protected memory space. It is located in conrol panel>system conrol panel>advanced settings> advanced>performance options. Default is for essential windows services. See picture. yours should be set that way.

Let us know what your current setting is.
