Short version … while attempting to access various files, I am prompted with an access permissions error. Disable avast and I can access the files.
Why and how can I correct?
Unblocking a Program. Open Avast Free Antivirus, then click “Antivirus” followed by “Settings.” You can paste the file paths you copied in the “File path” field where you see “(enter file path).” Click “Add” and the program will be excluded from all of Avast’s protection shields, including virus scanning.
This rather depends on the file/s location/s and file type/s (?) - see attached screenshot, click to expand.
This may well be the Ransomware Shield in action, a screenshot of the blocking in action might help.
