I know that it is the driver that runs Sound Max on my Intel 865GBF. I don't need it as I use Creative Lab Sound Blaster Live instead. It can be disabled in system settings.

I know that if you want to delete it, it isn't as difficult as everyone says. I'm not a computer guy, sop I don't know about removing registry items and such. So, in Spybot, after you have fixed the problem, go to recovery. You will see that spybot has backed up SMax4PNP. Just chose to "purge" this item. I haven't had it sence.
