[. . . ] Experienced users can, of course, accelerate anti-virus scanning process to the detriment of overall security by disabling the scanning of various file types, but we do not recommend doing so to users who want the best possible protection. To ensure maximum user protection, Kaspersky SMTP-Gateway recognizes more than 40 types of archives and installation packages, and can detect viruses in more than 350 different file formats. This is essential for anti-virus security because harmful executable code may be hidden inside files of any recognizable format. However, despite the daily growth in the number of viruses detected by Kaspersky SMTP-Gateway (approximately 30 new viruses daily) and the ever increasing number of recognized file formats, each version of our product functions faster than the previous one. This is achieved through the use of new unique technologies, such as iCheckerTM and i-StreamTM, developed at Kaspersky Lab. Each file is checked for viruses only once, during the 62 Kaspersky® SMTP-Gateway 5. 0 first scan. During subsequent scans the file is not scanned for viruses provided that it has remained unchanged since the last scan. Thus, the anti-virus application performance increases dramatically after the first file scanning. Kaspersky SMTP-Gateway will not work without a properly installed license key. If you haven't yet made a decision whether you wish to buy Kaspersky SMTP-Gateway, we can provide you with a trial key, which will work for a period of either two weeks or one month.
