You can read about it here and here.
It pertains to the Windows Update called Microsoft .Net Framework Assistant 1.0
Regarding the extension:
Microsoft has disabled the "uninstall" button on the extension. What's more, Microsoft tells us that the only way to get rid of this thing is to modify the Windows registry, an exercise that -- if done imprecisely -- can cause Windows systems to fail to boot up.
Be aware of this if you are getting popups about the Microsoft .Net Framework Assistant when using Firefox although as the first two articles describe, Mozilla has circumvented it.
