Okay, so recently I've been getting a problem with my computer not being able to display words correctly when I access a web page. Instead of showing the usual letters and words in English, everything shows up as musical notes and treble clefs. This doesn't happen on every page I go to. Note: I have had guitar pro and power tab software installed on my computer for about six months, could they have anything to do with the error? Any help will be greatly appreciated. Thanks.
