When using safari, chrome, firefox, whatever every so often I will start to get strange letters or symbols come up in the URL bar when attempting to do a search. I can never type in what I am looking for as it thinks I am trying to search in Swedish or Finnish or some language I don't speak. If I restart my computer (3 month old iMac) the problem goes away but it always ends up coming back later on in the day. I attached some sample pictures. In th first one I am trying to type Kolt and it wouldn't stop at the "t" and kept going with suggestions.
