Thank you for the timely response. FYI - before responding to this reply I opened Task Manager and watched the CPU usage while using Chrome to browse the web.
MsMpEng.exe was not as active as has been but did use up to 5% at times. However, my problem still persists and one problem that I did not note in previous text is
that when I re-direct to a different site, or back to Google home, there is an immediate termination - kinda like a dropped cell call. Also have tried IE - with same results.
Otherwise when offline, I have no issues with computer.
