DEVLDR is the driver for Sound Blaster Live!.
You have spyware.
I suggestions. Do the instructions on the following thread:
This will get rid of the spyware on your computer.
Install and update a virus program. I use McAfee but other are just as good.
Uninstall your Sound Blaster Drivers and re-install them. You might even want to get the latest version. Uninstalling is much better then just re-installing over the bad files.
Delete all of your history, cookies and files from IExplorer. Tools > Internet Options. Include all offline content.
Be sure you power off completely each time you need to re-boot. When you just re-start the RAM is still full of programs and other things...if one of them is spyware and/or virus you will reinfect your system and sometime bypassing your virus program.
Hope this helps.
