My search for a driver for my ujda330 CD/RW drive led me to this as a driver, but I can't seem to find it

It causes BSOD for AVG anti-virus rootkit check
This file interferes with AVG rootscan kit scanner and causes my computer to shut down during a scan. I was told to rename the file and perform a root scan by AVG. I have InCD as a cd burning software on my computer. Not worth the risk, I'm deleting it. My computer shuts down periodically now for some reason, running scans.
