Is Windows a Virus or a Bug?
(From: John Borchard (jb@dendritics.com))

Is Windows a Virus? No, Windows is not a virus. Here's what viruses do:

1. They replicate quickly - okay, Windows does that.

2. Viruses use up valuable system resources, slowing down the system as they
do so - okay, Windows does that.

3. Viruses will, from time to time, trash your hard disk - okay, Windows does
that too.

4. Viruses are usually carried, unknown to the user, along with valuable
programs and systems. Sigh... Windows does that, too.

5. Viruses will occasionally make the user suspect their system is too slow
(see 2) 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.

So Windows is not a virus.

It's a bug.
