Whilst I can't see exactly what is on your explorer screen, I have for some time been manually deleting these uniquely named folder, providing that they are at least a month old (or leaving the most recent one. This obviously comes with a health warning, left in place they can't really do any harm or take up a great deal of disk space. But deletion could have some ramification, I haven't experienced any problem in doing this, the choice is yours on how to proceed.
You would have to disable the avast self-defence to be able to delete them. Ensure that you enable the self-defence module when you have done.
Whatever you do don't remove the emupdate folder or any of its contents - even though some of there uniquely named .exe files may be old.
