I've removed the advice in this thread to use HijackThis to disable that startup. It will do it, but will delete the entry from the registry and that can't be easily reversed so it is not advisable to use HJT as a startup manager if you are just going to disable a startup here and there.
Most people use msconfig to do this, which is OK, but it is meant to be used temporarily for troubleshooting purposes. I prefer third party startup managers. So see our tutorial for some info on how to disable your startup this way:How To Use The Startup Database
There are plenty of other startup managers out there besides AutoRuns--myself, I prefer Mike Lin's Startup Control Panel
Let us know what happens.
