Remember, a lot of these maleware programs disable antivirus websites from appearing in your browser.
Either help this FReeper fix the problem, or shut the hell up. It is not at all difficult to go into the registry to fix this problem. Some laptops come with a loaded Trojan that keeps defaulting the browser to the unwanted engine.

That is not true.
Windows is a flawless virus.
