on your computer and, every time the file is
opened, the virus runs and once more seeks
out other files to infect.

not necessarily harm files. Instead, it
tries to copy itself so many times that
the whole system runs out of resources
and crashes.

managed to infect nearly 10% of all
internet connected computers, causing an
estimated $8 billion in damages.

intent - maybe letting someone
else access to your computer.
