2.) The .Net Framework Assistant also changes the User-Agent string of the Firefox browser, adding "(.NET CLR 3.5.30729)"
A Browser Helper Object [wikipedia.org] (BHO) is a DLL module designed as a plugin for Microsoft's Internet Explorer web browser to provide added functionality.
"BHO can be used to install additional features or functions that are useful, it can also be exploited [about.com] to install features or functions that are malicious. Some applications, such as the Google or Yahoo toolbars, are examples of good BHO's. But, there are also many examples of BHO's which are used to hijack your Web browser home page, spy on your Internet activities and other malicious actions."
