Chapter 29 Anti-Virus The following table describes the labels in this screen. Table 138 Configuration > Anti-X > Anti-Virus > Black/White List > Black List (or White List) > Add LABEL DESCRIPTION Enable If this is a black list entry, select this option to have the ZyWALL apply this entry when using the black list. File Pattern If this is a white list entry, select this option to have the ZyWALL apply this entry when using the white list. For a black list entry, specify a pattern to identify the names of files that the ZyWALL should log and delete. For a white list entry, specify a pattern to identify the names of files that the ZyWALL should not scan for viruses. OK Cancel • Use up to 80 characters. Alphanumeric characters, underscores (_), dashes (-), question marks (?) and asterisks (*) are allowed. • A question mark (?) lets a single character in the file name vary. For example, use "a?.zip" (without the quotation marks) to specify aa.zip, ab.zip and so on. • Wildcards (*) let multiple files match the pattern. For example, use "*a.zip" (without the quotation marks) to specify any file that ends with "a.zip". A file named "testa.zip would match. There could be any number (of any type) of characters in front of the "a.zip" at the end and the file name would still match. A file named "test.zipa" for example would not match. • A * in the middle of a pattern has the ZyWALL check the beginning and end of the file name and ignore the middle. For example, with "abc*.zip", any file starting with "abc" and ending in ".zip" matches, no matter how many characters are in between. • The whole file name has to match if you do not use a question mark or asterisk. • If you do not use a wildcard, the ZyWALL checks up to the first 80 characters of a file name.
