o Use heuristic analysis - (on by default): scan the content of the page to be
displayed using the heuristic analysis method (dynamic emulation of the scanned
object’s instructions in a virtual computer environment).
o Enable thorough scanning (off by default) - in specific situations (suspicions about
your computer being infected) you may check this option to activate the most
thorough scanning algorithms that will scan even those areas of your computer that
rarely get infected, just to be absolutely sure. Remember though that this method is
rather time-consuming.
o Maximum part size of a file to be scanned - if included files are present in the
displayed page you can also scan their content even before these are downloaded to
your computer. However, scanning of large files takes quite some time and the web
page download might be slowed significantly. You can use the slide bar to specify
the maximum size of a file that is still to be scanned with Online Shield. Even if the
downloaded file is bigger than specified, and therefore will not be scanned with Online
Shield, you are still protected: if the file is infected, the Resident Shield will detect it
immediately.
o Exclude host/IP/domain - you can type the exact name of a server (host, IP
address, IP address with mask, or URL) or a domain that should not be scanned by
Online Shield into the text field. Therefore only exclude hosts that you can be
absolutely sure would never provide dangerous website content.
