Hey @Umbra so I just installed the latest update but it says Avast protection is off when its not. I don't want to run both simultaneously but don't know if I would be protected. What should I do?
That issue has been reported at the Avast forum. You can check there if someone managed to fix it.

Some recommend a simple reboot, others say that they had to reinstall Avast.
