To remove the AVG toolbar in Firefox...

1. In the Firefox menu: Tools > Add-ons > Disable AVG Security Toolbar.
2. Restart Firefox.

Unfortunately on the 23 Jun 2010, AVG decided to send a message to all their PAID users advising them to install the AVG toolbar and change their search providers to Yahoo. By default - this message also sets up Yahoo as your search engine.

Side Notes:

When AVG re-installs it gives a page with two tickboxes to install the toolbar and to set Yahoo as the default search engine. At this point you need to stop and untick those boxes. Its easy to miss - and most people just click continue.

In Firefox you can uninstall the AVG Tool bar - through Tools/Add-ons/Extensions as mentioned above. But keep the AVG Safe Search enabled - as this is the bit that screens the sites.

Something else to note, AVG-Free does not give you complete protection. Those fake Antivirus2011 programs get through AVG free. Its better than nothing, but AVG free does not protect you from root kits. The Paid AVG does give you complete protection.

If you are running AVG-Free and you are having problems - address the AVG Free support [http://free.avg.com/au-en/support.] The forum is ok. Its a free product - so don't expect too much
