I made a virus once and observed what it did with my old laptop. I had to reinstall windows, so it kind of worked, but I have never used it on other computers.Making a Virus is one of my minor Dreams..........I made one using Visual Basic
It affected PC like it will not respond to anything and to restore ur PC back u will have to Unplug ur PC............That was my Mini Virus..........xdxdxdxdxdxd
