Selecting this option reduces the load on the gateway by skipping
safe file types. This option is selected by default.
Type the maximum number of nested content levels that
VStream Antivirus should scan.
Setting a higher number increases security. Setting a lower
number prevents attackers from overloading the gateway by
sending extremely nested archive files.
The default value is 5 levels.
