Hi, I have an Acer 5715Z laptop and it has some major/very annoying virus thing that is stopping me from basically doing anything. I have done so much stuff to try and sort this out, I never made disks (yeah, I know) and it came pre-installed with Windows Vista. I have it fine in safe mode so I can rescue all my stuff just fine. Basically I need to restore it to factory settings, how do I do this without using any disks? Thanks for replies and help.
