Sensitive Documents

AVG tends to select documents it considers to be sensitive without my knowledge, but how do I create a sensitive document or select and convert a basic document into a sensitive document?

Hello Albert.
Sensitive Data Shield scans and protects documents that may contain your personal data. After scanning, Sensitive Data Shield displays an overview of sensitive documents that were found on your PC. Usually, documents are sorted into several categories, such as:

Tax documents
Payroll documents
Employment documents
Plane tickets
Travel documents
Other sensitive documents

At the moment, it is not possible to convert a basic document into sensitive document.
AVG will automatically scans all the documents and categorize as sensitive based on the data present in it.
