There should be a drop-down list of three installation types:
Recommended (virtually everything), Minimal (all shields less the mail shield) and Custom, which as Craig mentioned has all boxes checked.
These options (installation types) have been available from avast 12.2.xxxx I believe hopefully they would still be there in 2281. I can’t say for certain as I’m waiting on this beta as I think it really is work in progress.
EDIT: As far as I can remember Custom installs always had everything checked (not many times when I did a clean install), mainly because I normally do a minimal install and had to uncheck those options I didn’t want.
Yeah Think Custom installs always had everything checked, it did on 12.3.2280 just a few moments ago, tried the beta twice on this Windows 10 Pro X64 System, this time corrupted my entire user account, so opted for a PC Reset, and choose to install 12.3 this time. Really a working in progress right now, Still have Windows.0ld folder though, if I can find the memory dump in there, would that be helpful to Submit to Avast Developrs?
