Get rid of the tuneup utlity not the driver. 99% of those "speed up my PC" programs do nothing except load spyware and the ones that don't either do nothing at all to help or make things actually slower. Even reputable ones like ccleaner should only be used if you have specific issues and a good tech recommended that program. I've seen systems stop working after someone ran ccleaner also when it removed a bit too many of what it though were un-needed registry keys.
If your computer is slow it's either
A. A slow computer that needs hardware updates or replacing.
B. Was loaded with a bunch of crapware like that tuneup utility, several antivirus programs instead of one, any other number of junk that you run across on the internet...
