ANTI-VIRUS PROTECTION OF YOUR

COMPUTER'S FILE SYSTEM

Your computer's file system may contain viruses and other malicious programs that persist for years, having initially

penetrated the computer from a removable disk drive or from the Internet, and never causing any trouble. But once the

infected file is opened, the virus will be activated immediately.

File Anti-Virus is the component that monitors the computer's file system in real-time mode. By default, it launches on

operating system startup, stays in RAM, and scans all files that are opened, started or saved on your computer and all

associated disk drives.

The scan process comprises the following steps:

1. Each attempt by a user or a program to access any file is intercepted by the component.

2. File Anti-Virus scans the iSwift (see section "Configuring additional settings" on page 37) database for

information about the file. A decision whether to scan the file is made based on the information retrieved.

3. The file is analyzed for viruses. Malicious objects are recognized based on the Kaspersky Anti-Virus databases.

These databases contain descriptions of all the currently known malicious programs and the means to neutralize

them.

4. Following the analysis, one of the following Kaspersky Anti-Virus operation modes may be applied:

a. If a malicious code is detected in a file, File Anti-Virus blocks the file and attempts to disinfect it. After

successful disinfection, the file will become accessible. If disinfection fails, the file will be deleted. When the

file is disinfected or deleted, a copy of it is placed into the backup storage (on page 78).

b. If a code that is similar to a malicious one is detected in the file but cannot be proved to be definitely

malicious, the file will be placed into a special storage area called quarantine (on page 75). The application

will attempt to disinfect it later using updated databases.

c. If no malicious code is detected in the file, it will immediately become accessible.

PAUSING / DISABLING FILE PROTECTION

You can disable File Anti-Virus and file protection on your computer using one of the methods described below. However,

before doing so you should determine why you want to disable the component. It may be possible to solve your problem

in another way, such as by changing the security level (see section "Selecting the file security level" on page 32) or by

disabling protection only for certain files.

For example, if you are working with a database that you know to be free from viruses, just specify the folder containing

its files as an exclusion (see section "Trusted zone creation" on page 27).
