see https://support.mozilla.com/questions/854647 : home page keeps reverting to http://www.searchqu.com/406 : refers to http://deletemalware.blogspot.com/2011/05/how-to-remove-searchqu-uninstall-guide.html ---- Unrelated to your question but your flash plug-in is at 10.0 r45 and is out of date, it should be at 11.0.1.152 check and install newer version from :http://www.adobe.com/software/flash/about/ Be careful when installing software or updates for/from Adobe and several other software providers, many are packaging crapware with their product. Only install the product you were planning to install. Do not install additional products: including -- "Free! McAfee Security Scan Plus" or "Google Chrome". Installing Google Chrome on your own and installing it because it is offered on the Adobe site are two different things. After you have updated your plug-in check all of them at :http://www.mozilla.org/plugincheck/ Also check http://kb.mozillazine.org/Problematic_extensions for potential problems.
