As I said before. Changes in the system restore only fully take place after a reboot.
That can make the difference
Eddy, that wasn't the issue... When my wife still had that problem, prior to "out of the blue sky" fix, I performed reboot on my wife's machine and still had same problem... Of course, I'll reboot, when avast! was asking all of us to reboot systems after program update. That's natural... to be true, I rebooted 2 or 3 times after avast! 4.5.542 update, and prior trying to turn ON the System restore feature. Still was locking up her system... so, no rules in this case...

Yes, maybe it's useless, and I don't use it either... but, we have to think of something... no matter if we use it or not, this is just coincidency we found out that it's not working properly... we have to take into consideration, since we found that issue, it may be few other things that doesn't work properly in combination of few latest avast! builds and Windows OS... I've noticed, many new users and forum members like to say: "Great, no problems here, everything works wonderful... thanks..."
I bet they didn't even try enabling/disabling System Restore... we won't know for sure, until everybody try that... same thing with all of us... maybe someone found something else, and we still didn't see his/her post about that issue. That doesn't mean everything works great...
I for sure, want to know what's going on with that issue, because no matter I don't use System Restore, as long as there is even just only one thing not working properly, we have to think... maybe there are some other things not working as they should work. Some info would be great. My wife's System Restore disappeared all of a sudden, but that doesn't mean we should close this issue now. It's obvious, there are some other people still experiencing same problem. That means, something is still wrong with it... we have to work on this one, 'cause it looks it's a tough one...
Cheers !
