Free Anti Virus does not start

Hi,

When I boot my PC (Win 10, 64 bit) Avast 11.2.2262 does not start at all.

I always have to start it manually. It used to start before a recent update.

Is there anything I can do?

Perform a repair of avast and check if it solved the problem.
If not, perform a clean installation of avast.

Thanks for the quick response.

Repair did not work so I need to uninstall and reinstall it, right?
