host process shutdown

Ok.. now I have gone back to look at the virus vault in avg. It did manage
to find the bug and lock it up.
It says it affects the svchost.exe file and changes permissions. That what I
seen and changed it back to my user details and the bug is ****ed. It shuts
down 3 services.
AtBroker.exe and smartlogon.exe were also effected. I am now going to change
permissions on them also.
Ok. AtBroker.exe had the permissions changed to "trusted installer" but
smartlogon.exe was normal. So I have now taken back my full control on
permissions.
At this stage that host process shut down has not appeared yet.
