Avast freezes during full virus scan

I am currently running Avast premium on Windows 10 x64. I have avast set to do a full scan at 2am every morning. Over the last few weeks, I have noticed that it freezes and doesn’t get past 30% on a full scan. I have attached a screenshot of the freeze. I have looked through the forums but haven’t seen anyone post about this. Any advice on this?

Try the following.
