The message box says Microsoft.NET Framework Assistant is a browser add-on which has a bad reputation among Avast users, and asks me if I want to
remove it. The box says browser add-ons are sometimes a privacy risk, and can also affect browser performance.
I have not intentionally downloaded or activated anything-on recently.
I am inclined to click the choice which says "Remove Bad Add-on" unless someone here at KF warns me not to.
Katzy's link says that the option in the Firefox browser to uninstall the add-on is disabled, and it is difficult to do manually (that is, it
involves the registry, in which a mistake can cause great harm).
I could try to uninstall the add-on from what is in Katzy's site, or I can tell my free Avast! to proceed to do it.
I am inclined to trust Avast! The box offering to do so is still up.
I used Avast! to remove the add-on. I haven't verified it, though.
Strangely enough, scholar, I just investigated my FF add ons, and did not find anything related to M$.NET, yet I use the .NET framework on my machine. I wonder if you tend to click on stuff, just because it "looks" useful.
I checked mine, too. Not there.
