How retro viruses are different from other viruses?

[Jojoking]

It was awhile ago when I saw it, but there is apparently something you can download and burn to a disk and it will delete just about everything from your computer to make reformatting easier. Anybody know what the website is? There are missing, necessary files on our desktop or there may have been a virus and now its all screwy. I just got a laptop so was able to transfer all the stuff I needed from the desktop to the laptop, so it'd be better just to reformat since I already have everything backed up here so to speak. unlock iphone
