[. . . ] 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. That has become possible due to new iCheckerTM. 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. This is a necessary sacrifice for the security and safety of your data. Other anti-virus products speed up scanning by excluding both viruses, which are less easily detectable or less frequent in the geographic location of the anti-virus vendor, and file formats that require complicated analysis (e. g. In contrast, Kaspersky Lab believes that the purpose of its products is to establish real and complete security for its users. Kaspersky SMTP-Gateway gives its users maximum protection. Experienced users can accelerate anti-virus scanning to the detriment Frequently asked questions 73 of overall security by disabling scanning of various file types, but we do not recommend doing so for users who want the best protection. For maximum user protection, Kaspersky SMTP-Gateway recognizes more than 700 formats of archived and compressed files. This is essential for anti-virus security, because harmful executable code may be hidden inside files of any recognized format. However, despite the daily growth in the number of viruses detected by Kaspersky SMTPGateway (approximately 30 new viruses appear daily) as well as the ever increasing number of recognized file formats, each subsequent version of our product functions faster than the previous one. That is achieved through the use of new, exclusive technologies, such as iCheckerTM, developed at Kaspersky Lab. Will my Kaspersky SMTPGateway work without it?No, Kaspersky SMTP-Gateway does not work without a license key. If you are still deciding whether or not to purchase Kaspersky SMTPGateway, we can provide you with a temporary key file (trial key), which will only work either for two weeks or for a month. When this period expires, the key will be blocked.
