The application will notify you when an infected or a possibly infected file is detected. If an infected or potentially infected
object is detected, a notification with a request for further actions will be displayed onscreen. You will be offered the
following:
quarantine the object, allowing the new threat to be scanned and processed later using updated databases;
delete the object;
skip the object if you are absolutely sure that it is not malicious.
CHANGING SECURITY LEVEL OF FILES AND MEMORY
The security level is defined as a preset configuration of the File Anti-Virus component settings. Kaspersky Lab
specialists distinguish three security levels. The decision of which level to select should be made by the user based on
the operational conditions and the current situation. You will be offered to select one of the following options for security
level:
High. Set this level if you suspect that your computer has a high chance of being infected.
Recommended. This level provides an optimum balance between the efficiency and security and is suitable for
most cases.
Low. If you work in a protected environment (for example, in a corporate network with centralized security
management), the low security level may be suitable. The low security level can also be set if you are working
with resource-consuming applications.
Before enabling the low security level, it is recommended to perform the full scan of computer at high security level.
If none of the preset levels meet your needs, you can configure the File Anti-Virus's settings (see section "Computer file
system protection" on page 41) on your own. As a result, the security level's name will be changed to Custom. To restore
the default component's settings, select one of the preset security levels.
To change the current file and memory security level, please do the following:
1. Open the main application window and in the top part click the Settings link.
2. In the window that will open, in the Protection section select the File Anti-Virus component.
3. Set the required security level for the component you have selected.
CHANGING ACTIONS TO BE PERFORMED ON DETECTED
OBJECTS
Based on the scan results, File Anti-Virus assigns one of the following statuses to the objects detected:
malicious program (such as, a virus or a Trojan);
potentially infected status when the scan cannot determine if the object is infected. This means that the
application detected a sequence of code in the file from an unknown virus, or modified code from a known virus.
If Kaspersky Anti-Virus detects infected or potentially infected objects when scanning for viruses, it will notify you about it.
You should respond to the threat by selecting an action on the object. Kaspersky Anti-Virus selects the Prompt for
action option as the action on a detected object which is the default setting. You can change the action. For example, if
you are sure that each detected object should be attempted to disinfect, and do not want to select the Disinfect action
each time you receive a notice about the detection of an infected or suspicious object, you should select the following
action: Do not prompt. Disinfect.
