Can't compile any code

All of a sudden I've been unable to even compile any Arduino code at all. Even the code with an empty setup and loop when opening a new sketch won't compile. Here's the compiler output. The compiler will take much longer than it used to (5+ minutes) to compile even the simple code I mentioned earlier, then say it's done uploading but no sketch will be on my Arduino. I've tried restarting my computer and uninstalling and reinstalling the newest version of Arduino.

I think the relevant part of the output is:

Try temporarily disabling your antivirus software to see if that's the cause of the slow compile(and maybe the error also).
