Hello, I asked this question on another forum and I received one answer, but I am still lost as to what this does and how it applies to me. After installing Microsoft’s priority update for the .net framework 3.5, I noticed that when I opened Firefox, it informed me an add-on was installed. When I looked, I saw the following: Microsoft .NET Framework Assistant 1.0 I have been unable to get a clear description of what this is or what it does. Anyone have any idea exactly what this does? Should I leave this alone or disable it? Am I just being paranoid? This is on a single system and the .net framework is required for a CAD program that I run. Thank you for any help on this.
