Hosts file random change

I am not sure why it happened my a large part of my host file changed.

Picture of change

Below is the original text in the hosts file.

Copyright (c) 1993-2009 Microsoft Corp.

This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

This file contains the mappings of IP addresses to host names. Each

entry should be kept on an individual line. The IP address should

be placed in the first column followed by the corresponding host name.

The IP address and the host name should be separated by at least one

space.

Additionally, comments (such as these) may be inserted on individual

lines or following the machine name denoted by a '#' symbol.

For example:

102.54.94.97 rhino.acme.com # source server

38.25.63.10 x.acme.com # x client host

localhost name resolution is handled within DNS itself.

127.0.0.1 localhost

::1 localhost

My main windows operating system is 8.1, it does not have that encrypted text, I don't have a windows 10 installation so I cannot test this for you, however, looking on the web there are no findings of the text you displayed in your picture.

Not sure if this relevant, maybe change your encoding type to UTF-8 since your using ANSI?

...or a late april fools joke?
