No, Windows is not a virus. Here's what
viruses do:
They replicate quickly. (Okay, Windows does
that)
Viruses use up valuable system resources,
slowing down the system as they do so. (Okay, Windows does that)
Viruses will, from time to time, trash your
hard disk. (Okay, Windows does that, too)
Viruses are usually carried, unknown to the
user, along with valuable programs and systems. (Sigh... Windows does that, too)
Viruses will occasionally make the user
suspect their system is too slow and the user will buy new hardware. (Yup, that's with
Windows, too)
Until now it seems, Windows is a virus but
there are fundamental differences: Viruses are well supported by their authors, are
running on most systems, their program code is fast, compact and efficient and they tend
to become more sophisticated as they mature.
