114 Kaspersky Internet Security 7.0
When entering a trusted address, you can create masks with the following
wildcards:
* – any combination of characters.
Example: If you create the mask *abc*, no URL contain abc will be
scanned. For example: www.virus.com/download_virus/page_0-
9abcdef.html
? – any single character.
Example: If you create mask Patch_123?.com, URLs containing that series
of characters plus any single character following the 3 will not be scanned.
For example: Patch_1234.com However, patch_12345.com will be
scanned.
If an * or ? is part of an actual URL added to the list, when you enter them, you
must use a backslash to override the * or ? following it.
Example: You want to add this following URL to the trusted address list:
www.virus.com/download_virus/virus.dll?virus_name=
For Kaspersky Internet Security not to process ? as a wildcard, put a backslash
( \ ) in front of it. Then the URL that you are adding to the exclusion list will be as
follows: www.virus.com/download_virus/virus.dll\?virus_name=
