Every time since the last update I turn on my computer I get this " Do you want to allow the following program from an unknown publisher to make changes etc" This program (wkufind.exe) keeps popping up on start up, I press yes when it pops up during start up to get rid of it but it becomes annouying when it pops up during startup everytime . I am running win 7 ultimate, I think this is for microsoft word update not sure. how do I stop this?
