Hello. I'm new to VirtualBox (downloaded the setup yesterday) and I wanted to install the Network files from the installer, but I get a warning saying that installing this will reset my connection and leave me without internet temporarily. Will it apply to everyone who's connected to the network or just me?
PS: I'm connected to the internet through Ethernet, thought that could help.

Will it apply to everyone who's connected to the network or just me?

It applies to the host that you are installing VirtualBox on. It is almost immediate though unless you have issues.
