Repeated MSAS Change alert

Every time I log into my "limited user" account. MSAS says an application has changed do you want to allow a change of the addition of the Google toolbar to internet explorer. c:/programfiles/google/googletoolbar2.dll I checked the box to remember this change and click allow but it comes back the next time I log in. Is this something I should be concerned about? I was hoping the new version was going to resolve this. Using most recent updated version 1.0.701 problem occurred with previous version also. XP pro SP2 with all patches, BoClean, Winpatrol, Taskcatcher, AVG Free, Zone Alarm Free, Spybot SD Teatimer

I upgraded my BOClean to the new version 4.20 and the problem with MSAS went away.
