Avast won't allow me to delete a closed word document

I have one word document in a folder. I cannot delete it. It is closed. I’ve checked in Task Manager and it is clearly not open. However I am told that it is in “in Avast” Whatever that actually means in unclear. The document is a template that I had not typed anything additional onto. I went into Avast and say little help in there, except I can see “shredder” I get the same message that the document is open in Avast. Ive tried using disk cleanup and have suspected thumbnail but none is showing in the folder. How else can I remove this folder and document? Having it there in my main folder is confusing to my filing system as its name is a name I wish to re-use and I just want it deleted.

Do you have avast with ransomware shield?

is it protected by ransomware shield >> https://support.avast.com/en-ww/article/Antivirus-Ransomware-Shield-FAQ

It would help if we knew the folder and the avast version that you are using ?

I too was thinking possibly ransomware shield. That however, would be dependant on if you had a version of avast that included the paid ransomware component and if that location was protected by the ransomware shield.
