When you have two 'file monitoring' apps accessing each other's scan space, they can interpret each other's access as edits and go into a CPU loop. Dropbox and any other sync client will do this. I generally look at AV as effectively useless and badly made, your system will speed up a lot in general (independent of dropbox) if you stop using it. > Some third-party apps access files in your Dropbox folder. Dropbox may interpret this access as edits to the files, and sync these perceived changes. If a third-party app continually requests access to your files, Dropbox will continue to sync, which will in turn lead to high CPU usage. > This loop usually occurs with third-party syncing apps, backup apps, and anti-virus or security software, or when a third-party app is installed within the Dropbox folder. > https://www.dropbox.com/help/desktop-web/high-cpu-usage https://www.dropbox.com/help/desktop-web/high-cpu-usage
