[. . . ] You can verify the proper operation of Kaspersky SMTP-Gateway using modifications of the EICAR "virus" only if your anti-virus databases were last updated on or after October 24, 2003, or has the cumulative updates for October 2003. Test "virus" modifications Prefix No prefix, standard test "virus"" CORR­ SUSP­ WARN­ Object type Infected. Suspicious (modified code of a known virus). 70 Kaspersky® SMTP-Gateway 5. 5 for Linux/Unix Prefix ERRO­ CURE­ DELE­ Object type Error when scanning the object. The object will be disinfected and the text in the infected file will be changed to CURE. The object will be deleted automatically. The first column of the table contains the prefixes that should be added to the beginning of the line in the standard test "virus" file (e. g. , DELE­X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*). After adding a prefix to the test "virus", save it to a file with another name, for example eicar_dele. com; assign names to all the modified "viruses" in the same manner. The second column contains the types of objects identified by the anti-virus application after you added a prefix. The actions for each type of object are defined by the application's settings customized by the administrator. CHAPTER 7. UNINSTALLING THE APPLICATION To uninstall Kaspersky SMTP-Gateway from server, you must be a privileged (root) user. If you are currently logged under a user account with lesser privileges, log on as root. When you are uninstalling the product, the application will be stopped, and all files and directories created during installation will be deleted. However, files and directories created or modified by the administrator, such as the application configuration file, notification templates, the quarantine directories, archives of received and sent messages, anti-virus databases, license key file, will remain. There are several different ways to run the uninstall procedure, depending on the package manager you used. If you installed the application from the rpm package, type the following in the command line to uninstall Kaspersky SMTP-Gateway: # rpm -e <package_name> If you installed the application from the deb package, type the following in the command line to uninstall Kaspersky SMTP-Gateway: # dpkg -P <package_name> If you installed the application from the universal package (tar. gz), type the following in the command line to uninstall Kaspersky SMTPGateway: # /opt/kav/5. 5/smtpgw/setup/uninstall. pl If you installed the application from the pkg package, type the following in the command line to uninstall Kaspersky SMTP-Gateway: # pkg_delete <package_name> After the application has been successfully removed from your server, you will see a corresponding message on your screen. CHAPTER 8. FREQUENTLY ASKED QUESTIONS This chapter contains a detailed discussion of questions most frequently asked by our users regarding the installation, configuration and operation of the application. Question: Is it possible to use Kaspersky SMTP-Gateway with anti-virus products of other vendors?We recommend uninstalling anti-virus products of other vendors prior to installation of Kaspersky SMTP-Gateway to avoid software conflicts. Question: Kaspersky Anti-Virus does not rescan files that have been scanned earlier. The application does not rescan files that have not changed since the last scan. The technology is implemented in the program using a database of file checksums. Question: Why does Kaspersky Anti-Virus cause a certain decrease in server performance, noticeably loading the CPU?Virus detection is a computationally intensive mathematical problem requiring structural analysis, checksum calculation and mathematical data conversions. Processor time is therefore the main resource consumed by the program, and each new virus added to the anti-virus database increases the overall scanning time.
