I just updated the Avast program (Windows 7, free version). After installing the update it restarted the computer and I got the window where it says “Almost done, click continue…” or something similar. Over on the left are there are the check boxes for installing Chrome and making it the default browser. I clicked them; nothing happened; they remained checked. I tried the X to close the window; it did not close. I went into task manager and attempted to stop the application; it did not respond and did not stop.
Surprise, surprise, when I finally clicked the Continue button the window closed, Chrome downloaded and installed and made itself the default browser. I immediately uninstalled it and reverted to my browser of choice.
Unacceptable.
