I don't have the Avast browser installed, so Bank mode isn't something I would need, unless it needs to update Avast completely in order for it to work. Also, I don't have my application update to automatic, I have it on "Remind me when an update is available" which just gives a pop up saying there's a new version available; it doesn't (shouldn't?) ask me to automatically restart.
I did do a restart (had to wait until my lunch hour as i'm working from home and use my computer for work), and noticed that the build did update to .767 (other numbers in the build version unchanged), but it didn't update that it until after the restart, which I guess would make sense but I can't remember if regular application updates do the same.
EDIT: I did a Change on Avast from Control Panel (thinking that would bring me to online repair), didn't add or remove any components and did a restart which changed my build number to ending .768. Did an actual repair, restarted (which didn't change the build number). Just to cover those bases to make sure nothing was broken. Hopefully I don't get a request to restart again. I could uninstall and reinstall but I did that three days ago and have done it several times over the last couple of months, so I don't know if that would have an effect. Also, shit's just too time consuming.
