For me, internet explorer opened ok from all programs, so the fix to this was as easy as restarting the computer, unpinning explorer from the task bar and repinning it. i’ve opened and closed it several times from the task bar and it’s working again.

i emailed customer care about the google chrome issue, it downloaded automatically with the avast update in the middle of the night. i would like avast to stop inflicting this program on me, i don’t need another browser.
