Yes, I uninstalled avast! (just as a precaution) and the update popped up upon reboot, then I reinstalled it. My wife wants to wait on hers, though, since she's less sure of the avast! settings she'd have to reconfigure/change.
I'm really surprised this hasn't been addressed yet!
Neither of us can update our motherboards yet (for me, dauntingly, manually). That might be weeks or months, though, if ever. I guess all we can do is be careful in the meantime.
