Go back to the System Services tab,start the Scanner Service.Then rightclick the sdtray icon(it's down by your clock),and Exit.
Now click over to the System Integration tab,scroll down to Tray Icon and start it,then click Apply and OK.The reason for that is because sdtray doesn`t show it unless you exit it and start again,but if the Scanner Service is active,then you should see AS + AV as Active.
After that can you reboot your computer to see if the Scanner Service comes on automatically when you boot into windows?
I might as well find out from you what your operating system is now,in case more needs to be done after that.
