REmove from Firefox Toolbar and windows control pannel

In order to uninstall a possibly unwanted extension, please do the following:

1. From the Firefox window click the Firefox button at the top left and select Add-ons, or, if the Firefox button is not shown, click the Tools menu and click Add-ons.
2. Once the Add-on Manager has opened in a new tab, click the Extensions button on the left side of the window.
3. You should now see a list of your installed extensions on the right side together with buttons on the right side of each extension.
4. To remove an extension from Firefox, simply click the Remove button. You should see a message that informs you about the successful removal of the add-on.
5. Note that some add-ons require a Firefox restart to be removed completely. To perform a Firefox restart after the add-on removal, click the Restart now link in the message.

Remove a toolbar that has taken over your Firefox search or home page

I have the same issue too - but this is an AVG issue not a FFX problem. like many other software houses, AVG have annoyingly begun bundling these things in with their product. When AVG does a programme update YOU need to ensure that automatic updates are disabled. look closely at the AVG dialog screen - dont just click OK. There are small tickboxes displayed where you can de-select the toolbar and safe search etc, but YOU need to turn em off before letting the update install.

You can, and will continue to have to remove the toolbar after every AVG upgrade as described, previously, but stopping the installation to start with is the real answer.
