if it's Windows, it's probably Software Reporter Tool (not part of Chrome on Mac or Linux?) which looks like it sits there, running and eating disk performance after starting and sitting idle on one about:blank tab. [edit: only extension I have installed in Chrome is Google Docs Offline. Software Reporter Tool is the same as the "Cleanup" tool/malware scanner noted by id_404 in this thread.] https://geekflare.com/google-chromes-software-reporter-tool/ https://geekflare.com/google-chromes-software-reporter-tool/ Open Task Manager, expand the Chrome task and look towards the bottom, and Disk column.
