The point of a paid license is to get features and capabilities that the free version does not have.
http://www.avast.com/en-us/compare-antivirusIn Pro, you get SafeZone, but not in free version.
A bit or so ago, user CraigB recommended an upgrade to a beta version.
Did you do a clean install of version 2014.9.0.2021 and select a
custom install after removing the old version by using aswclear.exe?
Or, did you do an upgrade within the avast user interface to get the latest version?
A clean install is recommended after removing the installation in place now.
First, be sure you have a copy of the license available before beginning a clean install.
Reason a clean custom install should be selected is so you can de-select the sandbox option when in custom install and avoid installing the problematic aswSnx.sys driver entirely. Doing so should clear this issue.
Then, you can configure your avast! hardened mode to Aggressive and that will take the place of the sandbox in protection. as user thekocks says.
