You might want to remove the Resident TeaTimer help, if selected. First open Spybot and then click on the "mode" tab. Then click on the "advanced" tab. Next click on the "tools" tab and then the "resident" tab. Remove the check next to TeaTimer. Leave the check next to the SD Helper. Now click on the "mode" tab again and click "default." This should stop the interference. If you continue to have problems, I would install HiJack This! and post a log of the scan results in the HiJack This! Topic here at Bleeping. These programs are compatible and this sounds more like a setting that needs to be changed or you could be infected with some type of malware.
You can get HiJack This! at; http://www.micaspecialties.org/lockdown.htm
view down the page to the Scrub up section and download all 4 of the programs if you do not have them already. They are well respected and free, so why not fix this problem right, while protecting yourself from future headaches?!
More than likely, you will need to post a HiJack This! log to verify that you are running a clean system.
