Configure the FortiGate unit to send an alert email when it blocks or deletes an
infected file. See “Configuring alert email” in the Logging and Message Reference
Guide.
Antivirus scanning
Virus scanning intercepts most files (including files compressed with up to 12 layers of
compression using zip, rar, gzip, tar, upx, and OLE) in the content streams for which
you enable antivirus protection. Each file is tested to determine the file type and the
most effective method of scanning the file for viruses. For example, binary files are
scanned using binary virus scanning and Microsoft Office files containing macros are
scanned for macro viruses.
FortiGate virus scanning does not scan the following file types:
• cdimage
• floppy image
• .ace
• .bzip2
• .Tar+Gzip+Bzip2
If a file is found to contain a virus, the FortiGate unit removes the file from the content
stream and replaces it with a replacement message.
If your FortiGate unit includes a hard disk and if quarantine is enabled for infected files
for the matching traffic protocol, the FortiGate unit adds the file to the quarantine list.
