I just upgraded my laptop and had to re-install Avast, which seems to have worked except for this error -
"This driver cannot be used due to compatibility issues
avast! self protection module
AVAST Software
You can get help on the Microsoft website. If a solution exists, follow the instructions to try to fix the problem."
Hopefully the update comes sooner rather than later, as we plan to get a majority (if not all) of our devices upgraded before school starts at the beginning of September.
