- SharePoint will only accept uploads from authenticated users reducing risks that an outside attacker could post any malicious files.
- SharePoint has an antivirus scanning engine built in to detect malicious files.
- If user's attempt to execute a malicious file in their synced folders, Outlook and Windows have warning pop-up dialogs requesting consent from the user before the malicious file can execute.
