Microsoft's Software is Malware

Other examples of proprietary malware

Malware means software designed to function in ways that mistreat or harm the user. (This does not include accidental errors.) This page explains how Microsoft software is malware.

Malware and nonfree software are two different issues. The difference between free software and nonfree software is in whether the users have control of the program or vice versa. It's not directly a question of what the program does when it runs. However, in practice nonfree software is often malware, because the developer's awareness that the users would be powerless to fix any malicious functionalities tempts the developer to impose some.

Microsoft Insecurity

Microsoft Sabotage

The wrongs in this section are not precisely malware, since they do not involve making the program that runs in a way that hurts the user. But they are a lot like malware, since they are technical Microsoft actions that harm to the users of specific Microsoft software.

Microsoft Interference

Various proprietary programs often mess up the user's system. They are like sabotage, but they are not grave enough to qualify for the word “sabotage”. Nonetheless, they are nasty and wrong. This section describes examples of Microsoft committing interference.

Microsoft Jails

Microsoft Tyrants

As this page shows, if you do want to clean your computer of malware, the first software to delete is Windows.
