PortalProtect has the following three types of scans:
Real-time scan
Manual scan
Scheduled scan
Each of these scanning options provides its own set of scan and blocking filters for:
Security Risk Scan,
File Blocking,
Content Filtering,
Web Reputation
and Data Protection
To protect your SharePoint environment, PortalProtect scans content searching for security risks and undesirable data. When PortalProtect makes a detection, it automatically takes action against the detection according to your configurations.
You can configure PortalProtect to scan specific targets and configure the actions it takes when it discovers a security risk or undesirable data. You can also configure PortalProtect to send notifications when it takes actions against security risks and undesirable data. Additionally, you can configure PortalProtect to save files to the Backup folder before it takes action on it. This is a safety precaution designed to protect the original file from damage.
Trend Micro recommends deleting backed up files once you have determined that the original file was not damaged and that it is usable after PortalProtect has executed an action on it. If the file becomes damaged or unusable, send it to Trend Micro for further analysis. Even if PortalProtect has completely cleaned and removed the virus itself, some viruses damage the original file code beyond repair.
