How can I get rid of Mysearchdial on Mozilla Firefox ? It doesn't appear in the add/remove list and I've uninstalled Firefox and reinstalled the latest version but Mysearchdial is still there !
Firstly your biggest issue is that you are using Windows XP which is about to lose all support on the 8th April 2014 . You should be considering a replacement computer running Windows 7 . You are the victim of a browser hijack and to remove this infection you will have to purchase a program called Spy Hunter 4 which will cost you $39.99 US which remove it for you. As the deadline draws nearer virus writers are rewriting their infections to take advantage of this.
