My computer keeps on running VERY slowly!?

When I shut it down it alway's says that it needs to wait for the program '' Device 10 notification window '' is still running what is this and why the heck is it running? I've ran all kinds of paid for antivirus software programs from Mc affee , Cogeco security services to xoft spy and they all say my pc is fine. Whats going on? any suggestions would be greatly welcomed!

what you should do is restore the program nd your computer will start normaly
upgrade it
I am wondering if 2 or more of your security software programs is conflicting with each other. I had that happen once--it was hell trying to get those removed.
