Hello, Hopefully someone can help with this. I have 2 files that I cannot open with notepad as they are in use. The files cannot be copied to qaurinteen or submitted to ESET. They files have been created may but update today 3pm, no one is home and the pc is off. The files are located in this location C:\Users\Stuart The files are called ntuser.dat.LOG1 ntuser.dat.LOG2 The files wont scan either, error opening. Should I be worried?
