In my opinion; software programs such as DriverMax, tend to screw with your computer more than help you, as you have seen for yourself.
If you need an updated driver for your computer, then I suggest you start your search at Dell's support website, here is the link for the latest drivers for your Acer E360:

Just click on 'Driver Download', and follow the steps afterwards, then you'll be good to go.
