You’re welcome.
To mca640 and everyone else who reads this post:
In cases like this we (as fellow users) can’t do much about the problem.
But we can checked things and give a (strong) indication if it is a false positive or not.
At the end it is up to avast to investigate and if needed fix things.
But please keep reporting things like this.
If someone doesn’t know that there is something wrong, they can’t fix it 
Please recheck latest version
