Some kind of (virus?) has attached to my Firefox and keeps changing my default search engine to Yahoo. I've run several antivirus programs to no avail. Frustrated, I tried to uninstall Firefox... but nothing happens when I click uninstall in Control Panel. Any ideas?

Hi kapalua93,

You should take a look at the Knowledge Base article Use the search bar in Firefox. Your default search might have been changed by a particular site. Sites like MSN, Yahoo, etc have been know to ask to become your homepage and change your search engine.

If the address bar search has been changed as well, you might want to take a look at Search the web from the address bar.

If that doesn't work you should look at the article How to fix preferences that won't save.

Finally, your issue may be because you've been hit with some Malware.

Hopefully this helps!

Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
