this plugin looks a bit odd to me. i believe this to be a component of an infection. this type of trojan is apt at key logging and redirecting. it would explain your problem as stated above. i would recommend that you procure a free copy of vundofix, as well as combofix for this "potential infection". follow the prompts for removal as they are given and report back if this infection is "recurring"
