Probably talking about this. In this picture, it has been updated three times ands is still saying it needs updating.
Probably not as the topic and sub-forum is about the Avast Driver Updater (paid product).
The problem your image shows is about updating the virus definitions, completely different.
Restart your system and see if that resolves it, if not try an Avast Repair, AvastUI > Menu > General > Troubleshooting > APP Repair. Restart your system after the repair.
If that doesn't resolve it, start your own new topic in the
Avast Free Antivirus / Premium Security Forum.
