File Shield

This Article Applies to:

  • Essential/Premium/Ultimate Business Security
  • Small Office Protection

 

File Shield is the main layer of Antivirus active protection. It scans programs and files saved on devices for malicious threats in real-time before allowing them to be opened, run, modified, or saved. If malware is detected, File Shield prevents the program or file from infecting devices.

We strongly recommend you always keep this shield turned on and only make configuration changes if you have an advanced understanding of malware protection principles.
