Concepto Que Es Un Antivirus

I opened a Dropbox file in Adobe Acrobat Premium and later discovered Dropbox has (quietly) given Adobe Acrobat Premium read/write access to my entire Dropbox folder hierarchy. Every Dropbox file has been automatically uploaded to the Adobe Document Cloud and deleting a file or folder in Adobe Acrobat deletes it from Dropbox and vice versa. This means that Dropbox and Adobe now sync with one another across the entire Dropbox folder structure. Is this the expected behavior?
