I installed a program called iMesh to play music on my computer via the internet. When I used Firefox now the search windows have been taken over by 'iMesh Web Search' and they don't bring up the same lists when I searched Firefox previously; e.g. it is very difficult to get 'Hotmail' to come up. I have uninstalled the iMesh program from the computer (not just deleted the icon), but my Firefox remains invaded. Please can you help?
