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.

Scan for Tracking Cookies
- (
switched on, by default
): this parameter of the
Anti-
Spyware
component defines that cookies should be detected during scanning; (
HTTP cookies are used for authenticating, tracking, and maintaining specific
information about users, such as site preferences or the contents of their
electronic shopping carts
)
·
Scan inside archives
- (
switched on, by default
): this parameter defines the
scanning should check all files even if they are stored inside an archive, e.g. ZIP,
RAR, ...
·
Use Heuristics
- (
switched on, by default
): heuristic analysis (
dynamic emulation of
the scanned object’s instructions in a virtual computer environment
) will be one of
the methods used for virus detection during scanning;
·
Scan system environment
- (
switched on, by default
): scanning will also check
the system areas of your computer;
Further you should decide whether you want to have scanned

All file types
with the possibility of defining exceptions from scanning by
providing a list of comma separated file extensions that should not be scanned;
or
·
Selected file types
- you can specify that you want to scan only files that
are possibly infectable (
files that cannot get infected will not be scanned, for
instance some plain text files, or some other non-executable files
), including
media files (
video, audio files - if you leave this box unchecked, it will reduce
the scanning time even more, because these files are often quite large and
are not too likely to be infected by a virus
). Again, you can specify by
extensions which files are those that should always be scanned.
·
Optionally, you can decide you want to
Scan files without extension
- this
option is on by default, and it is recommended that you keep it so unless you
have a real reason to change it. Files with no extension are rather suspicious
and should be scanned at all times.
Scan process priority
Within the
Scan process priority
section you can further specify the desired scanning
speed dependent on system resource usage. By default, this option is set to the
medium level of automatic resource usage. If you want the scanning to run faster, it
will take less time but the system resources usage will increase significantly during the
scan, and will slow down your other activities on the PC (
this option can be used
