It used to be a simple process to add a line to the hosts file either manually or by some third party software. Now it seems that all this has changed.
There are many "how-tos" on the net, but not that I have tried has worked. In the end, it always comes down to the following error when overwriting the existing hosts file (write protected or not):
The process cannot access the file because it is being used by another process.
Why do I keep getting this error message and how can I fix it?
Thanks
