Avoid new line comments when copy paste using Vim

I think you know what I'm talking about: you copy and paste something in Vim, and if there is a comment, all the following lines become commented.

How to avoid this behaviour? Use this command under vim

:set formatoptions-=cro

If you are in insert mode in Vim, you need to press ESC before entering this command.

Another solution should be:

:set paste (disable auto-indentation)
(paste what you have copied)
:set nopaste (enable auto-indentation)
