Microsoft .NET Framework Assistant (malware) has been blocked for your protection.

Why was it blocked?

This is not the Microsoft .NET Framework Assistant created and distributed by Microsoft. It is a malicious extension that is distributed under the same name to trick users into installing it, and turns users into a botnet that conducts SQL injection attacks on visited websites.

Who is affected?

All Firefox users who have this add-on installed.

What does this mean?

The problematic add-on or plugin will be automatically disabled and no longer usable.

When Mozilla becomes aware of add-ons, plugins, or other third-party software that seriously compromises Firefox security, stability, or performance and meets certain criteria, the software may be blocked from general use. For more information, please read this support article.
