Re: Virtual Device Driver format in the registry is invalid

Thanks for replying I did had a few spyware and virus which I clean out my register at lease I think. The First problem I had was downloading a program that did not work and could not delete. System Security "Do Not Download This Program" it will give you faust reading that you have several virus & trojans. The program will continue to pop up until your purchase it and will lockup your computer. I use Malarebytes Anti-Malware to fix the problem which my PC it working a lot faster. I think this is where the virtual pop up which lock up one of my CD/DVD writer.
