Windows 10: How to modify host file?? and is it safe to do it or resetting it to default

I want to modify a few entries of the HOST file but I don't know how to do it & I am not sure whether it is safe or not??what is a way to do it??

:)

 

think my hosts file got modified

like the title indicate' my AV found a modified host and it makes my internet to work slowly, I read in support forum that there is a solution by resetting the host file by opening notepad and put a text inside it then save the notepad and replace it with
the current host file. I want to know if I do so and resetting the host file, what changes will happen to my PC? I would need to sign in to all my websites again? or it will just reset without changing much?

this is the article that I found, maybe it will help you to understand better. hope it will help.

To reset the Hosts file back to the default, follow these steps:

1. Open Notepad. To do this, search for “Notepad” using
   Cortana, and then tap or click the Notepad icon.
   
2. Copy the following text, and then paste the text into the file:
   

1. Close Notepad.
   
2. Search for
   %WinDir%\System32\Drivers\Etc using Cortana, and then select the
   File folder icon.
   
3. Tap and hold or right-click the Hosts file, select
   Rename, and then rename the file as "Hosts.old".
   
4. Copy or move the Hosts file that you created in step 3 from the desktop to the
   %WinDir%\System32\Drivers\Etc folder. If you are prompted to
   enter an administrator password, select
   Continue

this is what I also saw in the forum in Microsoft that said

"If the Hosts file is wrong, because has been invalid modified by the user or by a malicious software, then causes Internet connectivity problems, such as re-directions to malicious websites, slow or no Internet access, etc. On all that cases you have to
fix the Hosts file by resetting it to its default clean state."

 

Hosts file editing

I have to jump in and say I use, and have used the host file for years. It's an easy way to take stress off of old name servers. I don't add everything, but major shares I do add to the host file. I've used the host file for some tunneling as well. I try to optimize my network as much as possible and I have a solid network. But Easy Rhino is right as well, you'll want to have everything he suggested as well. *Toast :toast:
