The following table describes the labels in this screen.

Table 121 Anti-X > Anti-Virus > General

LABEL	DESCRIPTION
Enable Anti-Virus	Select this check box to check traffic for viruses and spyware. The following table
and Anti-Spyware	lists rules that define which traffic the ZyWALL scans and the action it takes upon
	finding a virus.
Priority	This is the position of an anti-virus rule in the list. The ordering of your anti-virus
	rules is important as the ZyWALL applies them in sequence. Once traffic matches
	an anti-virus rule, the ZyWALL applies that rule and does not check the traffic
	against any more rules.
From	The anti-virus rule has the ZyWALL scan traffic coming from this zone and going to
	the To zone.
To	The anti-virus rule has the ZyWALL scan traffic going to this zone from the From
	zone.
Protocol	These are the protocols of traffic to scan for viruses.
	FTP applies to traffic using the TCP port number specified for FTP in the ALG
	screen.
	HTTP applies to traffic using TCP ports 80, 8080 and 3128.
	SMTP applies to traffic using TCP port 25.
	POP3 applies to traffic using TCP port 110.
	IMAP4 applies to traffic using TCP port 143.
Add icon	Click the Add icon in the heading row to add a new first entry.
	The Active displays whether the entry is enabled or not. Click it to activate or
	deactivate the entry. Make sure you click Apply to save and apply the change.
	Click the Edit icon to go to the screen where you can edit the entry on the
	ZyWALL.
	Click the Add icon in an entry to add a rule below the current entry.
	Click the Remove icon to delete an existing entry from the ZyWALL. A window
	displays asking you to confirm that you want to delete the entry. Note that
	subsequent entries move up by one when you take this action.
	In a numbered list, click the Move to N icon to display a field to type an index
	number for where you want to put that entry and press [ENTER] to move the entry
	to the number that you typed. For example, if you type 6, the rule you are moving
	becomes number 6 and the previous rule 6 (if there is one) gets pushed up (or
	down) one.
	The ordering of your rules is important as they are applied in order of their
	numbering.
