Avast didn't register with action center

I am on my dad’s computer updating a few things for him… I updated avast to 2015 and I noticed avast didn’t register with the action center instead it turned windows defender on… Any ideas?

Should I uninstall and reinstall or what I don’t know what to do in this situation…

Initally disable all shields for a few minutes and see if that cures it. If not then run a repair. Windows security centre is just throwing a wobbly :slight_smile:

I just ran virus def update after your post and it fixed the issue…

Hi,
have you restarted the PC just after the update. There might be a short period when Avast is unregistered from the Windows Security Center, but restart fixes this.
