I'm sure Avast has updated itself numerous times since the answer to how to pause it on Google was put up. That and Google's answers on tech can be very outdated a lot of the time.
If you want to pause the shields just for a minute for long enough to get something innocent done and not have to remember to put them back up, Go into Settings. The Shield Icon, don't look for words. Very top of main page is the toggle button to pause it, its green cause its ongoing. Just click it and the window will ask how long you want it paused for.
Also bear in mind there's a buffer window so you might actually have less time than what its offering. But only by like...thirty seconds or a minute of buffering time.
Mostly putting this up cause Google only just made the answer easy to find cause its only slightly outdated right now.
