IE popups while running firefox

so, i keep getting all of these internet explorer popups while i'm using firefox. obviously explorer is running in the background but every time i end it in the process manager it just starts right back up. i also keep getting voice ads saying i won an xbox or whatever other crap, but there aren't any actual popups displayed (just the voice). i don't really know how to get rid of this so any help would be greatly appreciated! here's the HJT log:
