I ran the 2006 suite with endless problems and at the end of the day was glad to be rid of it but during that time never got a reference to SAService application.
I've just had a look at the Mcafee site and notice that Site Advisor (could that be SAService application) is now integral with the 2007 suite. It was not in the 2006 suite.
You could try uninstalling just the site advisor element to see if that has any effect.You should,in fact be able to uninstall and reinstall each element of the suite separately.
Sorry to say I found the suite overbloated with elements I did not need.It would continually have activeX problems and it added about eight items to my start up menu which really slowed things down.
