I've been testing it for a few days now, I personally think it's fantastic. Definitely a huge step over the previous version. Loving how the sandbox decreases the heavy amount of Defense+ alerts we used to get using the older builds/versions. Also, huge upgrade to the AV engine. It actually stops a majority of the malware now. Glad how the AV can finally be put to good use instead of relying heavily on Defense+ to make every move.
I'd just wish they made the alerts easier to read.. Although they're much less common now, they're still difficult for the common user to understand.
