I just bought a new HP desktop with Vista 64-bit and recently installed Norton360 with no issues. However, once it finished scanning all of my discs and harddrives...I found it had erased all CD-ROM drives from the My Computer screen. When I went into the Device Manager, it showed both CD-ROM drivers were not working properly but that the drivers were installed and up-to-date! I'm not sure why Norton would corrupt the CD-ROM drivers...but it seems to be the case. Does anyone have a solution to this?
