Workaround then would be to disable and remove the AOS add-on in IE11. AOS does work in Google Chrome or Firefox without issues afaik, so you could try either to see if you get the protection you desire by switching browsers. Please consider use of Sandboxie in your browser for even more protection, see sig below, if you really want to stick with IE11.

If your AOS issue is relatively new, I’d check to see if the latest IE Microsoft security fix has something to do with it?
