Are Funwebproducts, including the official mywebsearch toolbar, adware, malware, adware, or spyware?

Is the Mywebsearch toolbar spam?

Yes, they are. Though they claim not to be, they use such things as cookies to track Internet usage, and employ advertising tactics such as 404 page redirection.

The tracking will result in a hit to your performance. Mywebsearch is listed in many anti-spyware programs as well. I would recommend that you stay away from it, as uninstalling it is a nightmare.
