110 Kaspersky Internet Security 7.0
Figure 31. Selecting a web security level
By default, the protection level is set to Recommended.
You can raise or lower the security level by selecting the level you want or editing
the settings for the current level.
To edit the security level:
Adjust the sliders. By altering the security level, you define the ratio of
scan speed to the total number of objects scanned: the fewer objects
are scanned for malicious code, the higher the scan speed.
If none of the preinstalled levels fully meet your requirements, their settings may
be customized. It is recommended that you select a level closest to your
requirements as basis and edit its parameters. This will change the name of the
security level to Custom. Let us look at an example when preconfigured security
level settings may need to be modified.
Example:
Your computer connects to the Internet via a modem. It is not on a
corporate LAN, and you have no anti-virus protection for incoming HTTP
traffic.
Due to the nature of your work, you regularly download large files from
the Internet. Scanning files like these takes up, as a rule, a fair amount of
time.
How do you optimally protect your computer from infection through HTTP
traffic or a script?
Tip for selecting a level:
Judging from this basic information, we can conclude that your computer
is running in a sensitive environment, and you are at high risk for infection
through HTTP traffic, because there is no centralized web protection and
due to the use of dial-up to connect to the Internet.
It is recommended that you use Maximum Protection as your starting
point, with the following changes: you are advised to limit the caching time
for file fragments during the scan.
