on by default
): check to activate the
Anti-Spyware
engine, and
scan for spyware as well as for viruses.
Spyware
represents a
questionable malware category: even though it usually represents a
security risk, some of these programs can be installed intentionally.
We recommend to keep this feature activated as it increases your
computer security.
Ø
Report enhanced set of Potentially Unwanted Programs
- mark to
detect extended package of
spyware
: programs that are perfectly ok
and harmless when acquired from the manufacturer directly, but can
be misused for malicious purposes later. This is an additional measure
that increases your computer security even more, however it can
possibly block legal programs, and is therefore switched off by
default.
Ø
Use heuristic analysis
- scan the content of the page to be
displayed using the heuristic analysis method, i.e. simulation and
evaluation of the scanned object's instructions in a virtual computer
environment. Therefore, it can even detect malicious code not yet
described in the virus database
(see
Anti-Virus Principles
).
Ø
Maximum file size 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: in case the file is
infected, the
Resident Shield
will detect it immediately.
·
Instant Messaging
- allows you to edit the components settings referring to
instant messaging (
e.g. ICQ, MSN Messenger, Yahoo ...
) scanning.
