I tried using my alt codes to make a different character and the alt codes commands seem to have changed. When I press alt+7 while trying to type an alt code online, it randomly opens the avg safesearch page, which I do not have installed (using chrome by the way), and it types the alt+7 character into the search. It never did this before for me, and also alt+4 and alt+6 seem to make pages go back and forward. For the past couple of hours I have been searching everywhere for what is happening, but nothing seems to work.
