It should be easy to find previous topics that you have been involved in using the 'Show new replies to your posts.' at the top left of the every page once you have logged in. Or click the Profile button in the Menu bar (big Orange bar at the top of pages), now click the 'Show posts' that will show all of your posts, not just ones that have had new posts since your last visit.

Not sure what you mean by clicking on icons, it would probably be the same for clicking on links ?
Try opening Chrome browser - I don't use chrome, so can't help practically - the add-ons or plugins control, find the Avast Online Security (AOS) and disable it - does that help ?
