Can someone please help me? I had dvd fab gold free trial installed on my computer and then changed to dvd fab platinum free trial, when i removed that i got the pcouffin.sys pop-up and I need to know what it is and if it will hurt my computer or not. How would I remove it? Some people have told me that it is a virus and other say it comes with dvd fab. Anyone that can help me I would greatly appreciate it. This also pops up when I try to reinstall dvd fab on my computer.
