Hi Sandy4 can you please try a repair of avast first, control panel / remove programs / click on avast then click uninstall and when you get the popup screen scroll to repair and click then click ok, see if that helps you first, if not you will probably have to try a clean install which means downloading a fresh copy of avast and saving then uninstall your current avast via remove programs and reboot, run ccleaner if you have it to get rid of any remnants then re install you new copy of avast.
