I would also suggest that you look at the VM Size as avast team members believe it gives a more accurate indication of memory usage. But there are times when that will be higher, though in the bigger scheme of things compare avast against other processes and it is far from a resource hog.

Don’t forget, memory is there to be used and it is windows that controls memory usage and when to release it.

You should also order the list by clicking on the Image Name column heading (and then use the scroll to place it at the top), this will allow you to crop the image showing only that which is necessary. This keeps image size down allowing you to post all three images in one post, see example image
